KATHMANDU: Flash floods and landslides in Nepal triggered by monsoon rains killed 15 people and injured 12 overnight while another 18 have gone missing, officials said on Saturday.

The latest deaths took to 30 the number of people killed in incessant rain that since Thursday has pounded much of the Himalayan nation tucked between China and India.

Officials said the Kosi River in eastern Nepal, which flows into the eastern Indian state of Bihar, had risen above the danger mark.
