Flash floods in the remote mountainous region of Ladakh in Indian Kashmir have killed 103 people, local officials say.

State police chief Kuldeep Khoda said Friday more than 370 others have been injured.

Police and paramilitary soldiers have pulled out hundreds of people from the mud and debris that have buried hundreds of homes but their efforts were hampered by gushing water and mud sweeping down from the steep mountainsides.

Telecommunication towers have toppled or are badly damaged while main highways connecting the popular tourist destination to the rest of Kashmir were only partially open.

Extensive flooding in neighbouring Pakistan has left at least 1,500 dead.
