More flooding is expected in Sudan, the country's chief weather forecaster warned on Thursday, after severe rains have killed 53 people and affected about 200,000.

"According to our information there is heavy rain in Ethiopia, and we expect flooding in the coming days," Abdallah Khiar told reporters.

Rains in Ethiopia feed into the Blue Nile river which runs to Khartoum, Sudan's capital.

The city has already been worst-hit by the heavy rains and flash floods which began in Sudan on August 1 and inundated several states, according to the United Nations.

More rain is expected in Khartoum through Friday, Khiar said.

The Blue Nile has already begun to overflow its eastern bank but is about one metre (yard) below the reinforced west bank, an AFP correspondent observed in east Khartoum.

Fifty-three people around the country have died and 40,000 families, or about 200,000 people, have been affected, Interior Minister Ibrahim Mahmoud Hamed told the same press conference.

AFP found residents of a community east of the Blue Nile camped beside the road on Wednesday because their homes had been destroyed or damaged in the flash flooding.

They appealed for more aid but Hamed told reporters "the situation is under control" and there is no need to declare an emergency.

"We have stocks of medicine, food and shelter material to support the affected people," he said.

Qatar, Ethiopia and Egypt have already flown in aid.

Pakistan floods affect 300,000: officials
Islamabad (AFP) Aug 18, 2013 - Heavy monsoon rains have triggered floods affecting more than 300,000 people across Pakistan in the last two weeks and killed 108 others, disaster management officials said Sunday.

"The rains affected 334,764 people, killed at least 108 people and wounded 104," a senior National Disaster Management Authority (NDMA) official told AFP.

The rains have hit 770 villages and completely destroyed 2,427 houses across Pakistan, he said.

The NDMA has established 44 relief camps in flood-hit areas to accommodate affected people, the official added.

Pakistan has suffered from monsoon floods for the last three years and has been criticised for not doing more to mitigate against the dangers posed by seasonal rains washing away homes and farmland.

Streets in all major cities including Karachi, Lahore and Islamabad suffer intermittent flooding due to downpours, damaging roads and private homes.

In 2010, the worst floods in the country's history killed almost 1,800 people and affected 21 million.
