Death toll in Nepal due to the devastating earthquake that hit the country, today rose to 1,807 with over 1,000 casualties in Kathmandu Valley alone.

A 7.9-magnitude earthquake jolted the Himalayan nation yesterday followed by several aftershocks and left a trail of death and destruction, flattening houses and buildings, including the iconic Dharhara tower and the landmark Darbar Square in the heart of the capital. Death toll in the quake has climbed to 1,807 while the number of injured has gone up to 4,721, according to a spokesperson of the Home Ministry.

Ten Mt. Everest climbers were also killed in an avalanche triggered by the earthquake. The calamity is said be the worst in over 80 years of Nepal's recorded history.

Two Indians, including the daughter of an Indian embassy employee, were among those killed in the powerful earthquake, an Indian embassy official said. A house in the Indian Embassy complex collapsed, killing the daughter of a CPWD employee. Death of another Indian was reported at Bir Hospital here.

Nearly 550 Indians have been evacuated by the IAF from earthquake-hit Nepal even as India stepped up its relief and rescue mission with 10 flights and 12 helicopters scheduled to carry specialists and equipment to Kathmandu today.

China too joined the humanitarian effort today, sending a 62-member search and rescue team to help Nepal.

The earthquake hit around 11:56 am with epicentre at Lamjung, around 80 kilometres northwest of Kathmandu, had its impact in several cities of Bihar, West Bengal and UP, and tremors were felt across vast stretches of east and northeast India. It was also felt in Southern and Western parts of India, China, Bhutan and as far as Pakistan and Bangladesh.

Several buildings, most of them old, in the densely- populated Kathmandu Valley collapsed, killing hundreds. Over 200 bodies have been retrieved from the debris of two-century old nine-storey landmark Dharhara tower in the centre of the capital. Kathmandu's Darbar Square, a UNESCO World Heritage site, was completely damaged in the quake which was the worst to hit Nepal and surrounding regions after the earthquake of 8.4 magnitude which occurred along the Nepal-Bihar border in 1934.
