Floods and landslides in Myanmar triggered by last week’s Typhoon Yagi and seasonal monsoon rains have claimed at least 226 lives, with 77 people missing, state-run media reported Tuesday.

The new figures push the total number of dead in Southeast Asia from the storm past 500.

The accounting of casualties has been slow, in part due to communication difficulties with the affected areas. Myanmar is wracked by a civil war that began in 2021 after the army seized power from the elected government of Aung San Suu Kyi. Independent analysts believe the ruling military controls much less than half of the country’s territory.

Typhoon Yagi earlier hit Vietnam, northern Thailand and Laos, killing almost 300 people in Vietnam, 42 in Thailand and four in Laos, according to the ASEAN Coordinating Center for Humanitarian Assistance. It said 21 people were killed in the Philippines, with another 26 missing.

The UN Office for the Coordination of Humanitarian Affairs, said on Monday that 631,000 people may have been affected by Myanmar flooding.
