ISLAMABAD: Pakistan authorities say more than 400 people have been killed by monsoon rains and flooding this year. 

The National Disaster Management Authority says 422 people have been killed and nearly 3,000 have been injured during the season of heavy rains.

About five million people have been affected by the resulting floods, according to statistics that were posted on the authority's website on Friday.

Pakistan suffers every year from flooding caused by massive monsoon rains that sweep across the country late in the summer and cause rivers and streams to overflow.

An official with the authority, Maj. Iftikhar Ahmed, told the AP that the rainfall this year was significantly less than in 2010, when catastrophic floods put one-fifth of the country under water and killed 1,985 people.
