Fifteen people including eight children who survived last year's massive earthquake in Pakistan died Thursday when monsoon rains triggered landslides and floods, police said.

A landslide buried several tents in the northwestern village of Daddar, some 240 kilometers (150 miles) from Peshawar, killing ten people and injuring five, district police officer Waqar Nazir told AFP.

"The victims were asleep," Nazir said, adding that the bodies had been retrieved from the debris. He said four children were among the victims and that five people died in one tent alone.

They had been living on the edge of a mountain since the October 8 South Asian earthquake, which killed around 75,000 people and left more than three million homeless.

Separately four children and a woman were killed when a flood swept away temporary shelters for quake survivors built on the bank of a stream in the scenic Alai Valley, 30 kilometres northeast of Dadar.

"They were washed away by the flood waters. The bodies of the victims have been recovered," said local policeman Mohammed Ayaz, adding that the dead were all from different families.

Aid agencies have warned that mountains covered with huge cracks caused by last year's gigantic 7.6-magnitude temblor could be susceptible to landslides and monsoon downpours.

Twelve quake survivors died in a landslide near Muzaffarabad in Pakistani Kashmir on July 24, while other landslides blocked the only route between the city and the scenic Neelum Valley.

Incidents blamed on the annual monsoon rains have now claimed around 110 lives in Pakistan since they started early last month. In neighbouring India they killed more than 300 people.
