Severe monsoonal flooding has caused widespread devastation across Pakistan, destroying homes and sweeping away entire villages.

A deluge of rain triggered floods and landslides, sweeping people away and flooding and destroying homes, officials said.

At least 21 people have died in monsoon rain-related incidents in Pakistan, authorities said, pushing the nationwide death toll over the last week above 400 as floods and landslides continue to devastate large parts of the country.

Pakistan has been grappling with widespread torrential rains in almost all parts of the country that have wreaked havoc and left over 700 people dead and hundreds injured. The deluge crippled the already dilapidated infrastructure, damaging houses, roads, and commercial centres.

Pakistan has received higher-than-normal monsoon rainfall this year, triggering floods and mudslides that have killed more than 540 people since June 26.
