The death toll from landslides and flooding in the Philippines triggered by Tropical Storm Megi has risen to at least 115, as search teams found more bodies in mud-buried villages.

Eighty-six of the casualties were in Baybay, a mountainous area prone to landslides in central Leyte province, where 236 people were also injured, the city government said in a report.

Megi was the first tropical storm this year to hit the Philippines, an archipelago of more than 7,600 islands.

Dozens of people are still missing and feared dead after several days of torrential rain with tens of thousands of people forced into evacuation centres.

Emergency teams retrieved dozens of bodies from the coastal village of Pilar, which was destroyed by a landslide on Tuesday.

At least 26 people were killed there and about 150 remain missing, authorities said, with little hope of finding anyone else alive.

Many of those who died had hiked up the mountain to avoid flash floods, villagers told the AFP news agency.

Pilar fisherman Santiago Dahonog, 38, said he rushed into the sea with two siblings and a nephew as the mud hurtled towards them
