PESHAWAR, Pakistan (Reuters) -Rescue workers on Tuesday recovered more bodies from a mountain village in northwest Pakistan where flash floods triggered by a cloudburst brought down homes and buildings, bringing the death toll there to at least 20, the local district commissioner said.

Heavier than usual rains and sudden cloudbursts during this monsoon season kill more than 300 people in recent days.

Across Pakistan, monsoon rains that began in late June have been heavier than usual, killing at least 645 people. Four hundred of those deaths were in the northwest alone, where narrow valleys and river-carved gorges funnel rainwater into sudden torrents.

More than 200 fatalities were reported in the Buner district of the northwestern Khyber Pakhtunkhwa province. The fatalities include 28 women and 21 children, the province's Provincial Disaster Management Authority said.

In just minutes, a torrent of water and rocks swept down on the village of Dalori, destroying at least 15 houses, damaging several others and killing nine people

China said on Monday it had not received reports of any Chinese casualties in the deadly floods that have swept across Pakistan since late last weekend, killing hundreds, leaving many missing, and displacing hundreds of thousands.
