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

Rescue operations using boats and helicopters, supported by Thai Navy SEALs, are underway to reach those trapped in flood-hit areas. Floodwaters have begun receding in some parts, but many riverside settlements remain submerged.

The Global New Light of Myanmar reported on September 15 that as of September 13 evening, flooding and landslides triggered Typhoon Yagi in the country had left 74 and 89 others missing.
