南苏丹乌书勒地区遭洪水淹没

Some 57,000 people have been forced from their homes because of dramatic floods in south-western Sudan over the past month, health officials say.

苏丹卫生官员称，过去的一个月中苏丹西南部地区大约57000人因洪水被迫离开家园。

Rivers near Aweil have broken their banks because of the heavy rain

Heavy rains have left Aweil, the main town of Northern Bahr al-Ghazal province, largely under water.

A BBC correspondent says the floods pose（造成，形成） another challenge to the already delayed voter registration¹.

Southern Sudan is voting on whether to secede²（脱离，退出） from the north in a referendum（全民投票） in January.

Challenge

The BBC's Peter Martell in Southern Sudan says the floods add to the woes³ of a grossly（很，非常） under-developed region still struggling to rebuild itself after the brutal⁴ two-decade war with the north.

"The rains are going to continue up until October, so the situation may get worse," Southern Sudan's Health Minister Luka Monoja warned.

"A serious situation has developed in Aweil - more than three quarters of the town is flooded and so many houses collapsed⁵.

"We saw that all the people were chased out of their houses, and were now living on the road, because the road is the only area in the town that is raised."

Our reporter says the southern government and aid agencies have been working to support those displaced（无家可归者） , but the challenge is enormous.

The United Nations has already provided some kind of food assistance to almost half the population of the south this year, he says.
