Pakistan's commercial capital, Karachi, has been paralysed by floods as torrential rain continues to lash southern Sindh province.

Schools have shut down, many markets were forced to close and commuters had to abandon their vehicles as rain water flooded the streets.

Villages across the province have been inundated as canals have been breached and water has not adequately drained.

Many in the region are still recovering from last year's devastating floods.

Millions were displaced across the country and about 2,000 people died as torrential monsoon rains in 2010 caused rivers to burst their banks, washing away homes and property. Sindh was one of the worst affected regions.

Some aid officials have said this year's flood situation is as bad as the devastation last year.

Then, a vast body of water flowed down the country, bursting the banks of the River Indus and hitting surrounding areas. This year's floods are caused by rainfall - two weeks of it so far - so the impact is far more widespread.

Pakistan's disaster management chief warned on Monday that the situation is worsening each day as water levels are rising because of poor drainage.
