At least 102 people are now thought to have been killed by floods in and around the south-western Nigerian city of Ibadan, the Nigerian Red Cross says.

尼日利亚红十字会宣称，西南部城市伊巴丹发生洪灾，至少102人死亡。

Floodwater, resulting from heavy rains that began on Friday, damaged three bridges and caused a dam to overflow¹（泛滥） , submerging buildings across the city.

Most of the victims were children.

"I think in the process a lot of [houses] were washed away by the rainwater," said Umar Mairiga, a Red Cross official.

He said that some victims had been trapped in collapsed² buildings.

Although flooding is common in Nigeria during the rainy season, meteorologists（气象学家） say this year's rains have been particularly heavy.

Last year, about 500,000 people were displaced nationwide.

The flooding over the weekend in Ibadan, 150km (90 miles) north of Lagos, was exacerbated³（加重，恶化） by rubbish and debris⁴ clogging⁵（堵塞） drains in the city.

About 2,000 residents have so far been displaced.
