SRINAGAR, India (AP) — The death toll from severe flooding in Indian-controlled Kashmir has risen to at least 28 people, as authorities asked for help from federal rescue officials as relentless rains continue to lash much of the Himalayan region, forcing thousands to abandon their homes in search of shelter.

Officials said Friday that the death toll from flooding and landslides caused by for four days of rain included two bodies recovered after a bus carrying more than 50 members of a wedding party that was swept away into a stream Thursday. Four passengers managed to swam to safety and rescue workers are searching for the others.

The region is witnessing its worst flooding in over two decades.

Meanwhile, Pakistani officials say heavy monsoon rains have killed 40 people across the country as the government warned of more flash flooding over the weekend.

Ahmad Kamal, a spokesman for the National Disaster Management Authority, said Friday that 13 people died when roofs collapsed in the eastern city of Lahore the previous day.

The rains triggered landslides that killed six civilians and three soldiers in the Pakistani-administered Kashmir on Thursday.

Heavy rains also lashed the capital, Islamabad, where thousands of opposition supporters have camped outside the parliament for weeks, demanding Prime Minister Nawaz Sharif resign over alleged voting fraud. The protesters used makeshift tents made from plastic sheets to shelter from the rains.

Pakistan regularly suffers from flooding during the monsoon season. In 2010, flash floods killed 1,700 people in Pakistan.
