Vietnam urges factories to cut output as Hanoi chokes on smog

  • The Southeast Asian country has been suffering from severe air pollution for years, especially in Hanoi

HANOI: Industrial plants in the Vietnamese capital of Hanoi have come under renewed pressure to scale back their operations as authorities respond to a week of heavy and hazardous smog in the city.
Vietnam’s Ministry of Health earlier this week urged power, steel and chemical plants to cut output when the air quality index exceeds 200. The index gauges the volumes of hazardous small particles known as PM2.5 that are in the air.
The AQI hit 243 midday on Thursday, putting Hanoi fourth on the list of the world’s most-polluted cities, according to AirVisual, which provides independent global air pollution information via a phone app.
The city has topped the list on a number of occasions this week, according to the app, a position it also held in January.
The Southeast Asian country, a regional manufacturing hub which is urbanizing rapidly, has been suffering from severe air pollution for years, especially in Hanoi.
“My eyes are itchy, and there’s always a blanket of smog that blocks my vision,” said Hanoi resident Pham Thu Giang, 30. “I have to wear a mask all the time.”
The authorities have identified transportation, industrial production, construction activities and the burning of garbage and agricultural residue as the main sources of air pollution in the city.
“Gasoline-powered motorbikes are used widely in Hanoi, making them a major source of air pollution,” Le Thanh Thuy, an official of the city’s department of agriculture and environment, told local media on Thursday.
The city will impose partial bans on gasoline-powered motorbikes in downtown areas from mid-2026 and will gradually expand the ban thereafter to fossil-fuel-powered cars.
“The current air conditions are very dangerous for the capital Hanoi,” said 75-year old resident Luong Van Toi. “I feel very tired.”
If Hanoi’s AQI is converted into actual PM2.5 concentrations, the pollution this week could be as much as 50 times the 5-microgram/cu m level recommended by the World Health Organization.

Two killed in suicide attack targeting security forces in Pakistan’s northwest

ISLAMABAD: Two security personnel, including an officer, were killed, while multiple others sustained injuries when a suicide blast targeted their vehicle in Pakistan’s northwestern Khyber Pakhtunkhwa (KP) province, a police official said.

The suicide bomber hit his explosive-laden motorbike into an armored vehicle of security forces in Sara Darga area of KP’s Bannu district, according to a local police official who requested anonymity.

No group immediately claimed responsibility for the attack, but the Pakistani Taliban, or the Tehreek-e-Taliban Pakistan (TTP), have carried out similar assaults in the region in past.

“The attack had damaged the armored vehicle, causing deaths and injuries,” he told Arab News, adding that they suspected the Pakistani Taliban to be behind the attack.

Pakistan has struggled to contain a surge in militancy in KP, which borders Afghanistan, in recent years, with militant groups, particularly the TTP, frequently targeting security forces, law enforcers and government officials in the region.

Earlier this week, Pakistani Taliban militants rammed an explosive-laden vehicle into a checkpoint jointly manned by security forces and law enforcement agencies in KP’s Bajaur district, killing 11 security personnel among 12 people, the Pakistani military’s media wing said.

Islamabad accuses Afghanistan of allowing the use of its soil and India of backing militant groups for cross-border attacks against Pakistan. Kabul and New Delhi deny this.
