The Pollution Control Department (PCD) under the Ministry of Natural Resources and Environment announced on April 30, 2025 that the third round of sediment sampling from the Salween River conducted between March 24-27 showed continued arsenic contamination. Samples were collected from monitoring points SAL08 (Ban Tha Ta Fang) through SAL13 (Ban Sob Moei) in Mae Hong Son Province.

Analysis results revealed that arsenic (As) levels at all six monitoring points exceeded the severe safety standard of 33 mg/kg, with concentrations ranging from 41-82 mg/kg. The highest reading of 82 mg/kg was recorded at SAL09 at the boundary between Sob Moei and Mae Saliang districts, while SAL08 measured 49 mg/kg, SAL10 measured 43 mg/kg, SAL11 measured 55 mg/kg, SAL12 measured 41 mg/kg, and SAL13 measured 50 mg/kg.

Testing of tributary water quality also revealed contamination in certain areas. The Mae Samlab River showed 16 mg/kg of arsenic, the Mae Yuam River contained 17 mg/kg arsenic along with 56 mg/kg chromium and 25 mg/kg nickel, and the Mae Pai River had 11 mg/kg arsenic. The Mae Po and Mae Kong Ka rivers tested within acceptable standards. Other heavy metals including lead, cadmium, copper, zinc, mercury, and manganese remained within safe limits.

Although current aquatic animal samples still fall within safe consumption levels, the PCD warned that arsenic accumulates in the food chain over time. Authorities recommend always cooking food thoroughly, avoiding repeated consumption of the same aquatic species, reducing intake of bottom-dwelling creatures like shrimp and shellfish, and avoiding fish organs, which are primary accumulation sites for contaminants. The department will continue monitoring water quality and coordinating with relevant agencies to protect public health.

Iran's Football Federation has announced that its officials were barred from entering Canada, preventing them from attending an FIFA meeting in Vancouver on April 30 ahead of the 2026 World Cup. The federation stated that a delegation led by President Mehdi Taj had obtained official visas to travel to Toronto but were denied entry by Canadian authorities, citing inappropriate conduct by immigration officers.

According to Iran's IRNA news agency, Taj's visa was approved on Monday but revoked on Tuesday because he is a former official of the Islamic Revolutionary Guard Corps (IRGC), which Canada designates as a terrorist organization. The Canadian government responded by stating: "While we cannot comment on individual cases due to privacy laws, our government has consistently maintained that IRGC members are not permitted entry to our country."

Canadian Foreign Minister Anita Anand clarified that the ban was not intentional, saying "It was not a direct order from me, but I understand that permission to travel to the country was revoked. It happened unintentionally, and I will have the Immigration Minister explain further." The 2026 World Cup will be co-hosted by Canada, the United States, and Mexico, launching on June 11, though Iran's participation remains uncertain following recent military tensions with the United States.

A female police officer affiliated with the Metropolitan Police Bureau filed a complaint after being taken to a budget hotel on Khlong Prasap Road by a male colleague from Pak Kret Police Station on February 18. After she contacted her mother for help, her commando boyfriend discovered the incident and confronted the officer, leading to her being dropped off at a shopping mall instead. The case was filed on February 19 but showed no progress, prompting the couple to go public through media.

The accused officer has since been reassigned to document work with no public-facing duties and was absent from duty on the day reporters visited. Police Station Commander Pol.Col. Adirek Thonggamaekeo stated that he received the complaint in February and immediately began investigating, conducting victim interviews, medical examination, collecting clothing for DNA analysis, and questioning witnesses. He explained that delays were due to waiting for forensic results, which were only recently returned on Monday. The case is now being compiled for submission to prosecutors. The commander emphasized that the investigation is thorough and asserted that whoever is guilty will face consequences without favoritism. Until the court decides, he imposed administrative measures limiting the officer to document delivery duties only to maintain fairness. The commander assured the victim of justice, stating that guilt will be prosecuted according to evidence and there is no protection being offered.

CHIANG MAI — 30 April 2026, Air quality in northern Thailand's Chiang Mai province is showing signs of improvement as the number of wildfire hotspots declines, officials said.

At a provincial meeting on wildfire and PM2.5 pollution mitigation held in Chiang Dao district, Vice Governor Siwakorn Buapong said efforts were being stepped up to accelerate pollution reduction plans at the local level.

Authorities reported that the VIIRS satellite system used to detect hotspots is temporarily unavailable, but data from the NOAA-20 satellite identified two hotspots on the morning of 30 April in Mae Wang and Omkoi districts. Cumulative figures from 1 January to 27 April showed 10,849 hotspots, already exceeding the province's target for 2026.

Despite this, air quality readings have gradually improved, with some monitoring stations reporting levels in the "green" category.

Weather forecasts for May indicate that the first half of the month will remain hot and humid, with frequent thunderstorms, before transitioning into the rainy season in the latter half, bringing lower temperatures and increased rainfall.

Authorities said law enforcement efforts against illegal burning between 1 January and 29 April resulted in 240 cases and 257 suspects. Offences included open burning in communities, forest law violations, roadside burning and breaches under national park, forest reserve and public health laws. Most cases have resulted in fines, with a small number forwarded for prosecution and others still under investigation.

The meeting also urged local administrative organisations to urgently submit integrated pollution reduction plans at subdistrict level, aligning with community strategies. These plans are to cover six key areas, including forest fire management, land and forest use, agricultural burning reduction, waste and carbon reduction, public health protection, and community participation, as part of Chiang Mai's 2026–2028 pollution control action plan.

At 4:30 PM on April 30, 2025, at the Klong Luek border checkpoint in Aranyaprathet District, Sa Kaew Province, Army Commander General Pana Klaiypodthukkha and Army News Bureau Director General Theeranun Nuntkhwang authorized Colonel Worwech Wonmongkol, director of the Army News Bureau's Foreign Relations Office, to coordinate with Cambodian authorities for the repatriation of 635 Thai nationals accused of involvement in online fraud schemes. The handover took place under military diplomatic protocols in cooperation with the National Police Office, Immigration Police, the Ministry of Social Development and Human Security, the Ministry of Labor, and the Ministry of Public Health.

Of the 635 individuals returned, 592 held valid passports while the remainder had their documents sent for visa extensions. All worked in the same location—a 13-story twin building called Building F situated opposite Roengklua Market. Following the handover, all Thai nationals must undergo NRM (victim and offender identification) screening to determine who was trafficked into the work and who willingly participated in defrauding other Thai citizens. Officials will also conduct criminal record checks and conduct approximately 70-80 questions per person during detailed vetting procedures.

This operation aligns with the Joint Statement signed by both countries on December 27, 2024, aimed at strengthening confidence and elevating bilateral relations, particularly in combating transnational crimes including online fraud and human trafficking that impact economic and social security.

Brig. Gen. Benjaphol Decharitwoungsa Na Ayutthaya, commander of the Northeastern Forces under the First Regional Army Command, characterized the development as positive, suggesting Cambodia may be demonstrating sincerity, though he expressed uncertainty about the final numbers. As the border area commander, he arranged to facilitate the opening of the Klong Luek checkpoint.

Journalists at the border reported that Cambodia had coordinated to deliver approximately 300 Thai nationals in the first morning batch around 9:00 AM, but by 4:30 PM, the handover still had not begun. Thai officials from immigration, social development, public health, and military units remained stationed at various points along the Klong Luek border checkpoint awaiting NRM screening procedures. Cambodia attributed the delay to overnight mass arrests of call center gangs, requiring multiple buses to transport Chinese nationals to Siemreap, leaving insufficient vehicles to transport Thai nationals. They requested additional buses from Banteay Meanchey province, which required travel time to Poipet.

Bank of Thailand Governor Vithaya Ratanakosr stated that Thailand's current economy should not be a cause for concern regarding stagflation, as inflation is unlikely to remain at elevated levels long enough to impact the economic structure. Economically, stagflation requires three key conditions: low economic growth coupled with high inflation sustained over an extended period. The Monetary Policy Committee did not discuss stagflation at its April 29 meeting, though some observers believe Thailand has already entered this phase based only on low growth and high inflation—a potentially flawed assessment. "In foreign economies, stagflation typically directly impacts employment, reducing employment rates or increasing unemployment. However, Thailand currently shows no signs of employment reduction. When both key criteria are considered together, Thailand is not in stagflation," the Governor explained. Stagflation occurs when economic growth stalls alongside high inflation and elevated unemployment, creating economic stress.
