NAIROBI, Kenya (AP) — Kenya has postponed the reopening of its schools by one week due to ongoing flooding caused by heavy rains, as flood-related deaths since mid-March in the East African country neared 100.

Some schools remained “adversely affected” by the flooding, the Education Ministry said Sunday night. Local media reported that more than 100 schools were flooded, some with collapsed walls and roofs blown away.

All schools were set to reopen on Monday but will now open on May 6.

Ninety-three people have died in the flooding in Kenya and that number is expected to rise after a boat capsized in the northern Garissa county on Sunday night. The Kenyan Red Cross said it had rescued 23 people from the boat, but more than a dozen people were still missing.
