Floods and landslides triggered by tropical cyclone Seroja in a cluster of islands in southeast Indonesia and East Timor have killed 113 people, with many still unaccounted for and thousands displaced, officials said on Monday.

At least 86 deaths were reported on several islands in Indonesia’s West and East Nusa Tenggara provinces, while 71 others were missing, after the cyclone brought flash floods, landslides and strong winds amid heavy rain over the weekend, disaster agency BNPB said. In East Timor at least 27 people were killed by landslides, flash floods and a falling tree, while 7,000 were displaced, its government said.

“We are using rubber boats to find bodies at sea. In several villages, flash floods hit while people were sleeping,” Thomas Ola Langoday, deputy head of Lembata district government, told Reuters by phone.
