At least 98 people are still missing in addition to 160 confirmed dead a week after floods ripped through a town in central Nigeria, the national emergency agency said on Wednesday, as hopes of finding survivors fade.

Flooding in Nigeria that submerged a town in a crucial agricultural region has displaced thousands of people, damaged farmland and claimed nearly 200 lives, the nation’s emergency agency said Tuesday.

The death toll from devastating flooding in a market town in Nigeria’s north-central state of Niger rose to at least 200 on Sunday, a local official said.
