Helicopters brought aid to Afghanistan's Kunar province on Monday after a strong earthquake devastated the area, killing 800 and injuring thousands more.

Near the helicopters, doctors treated people who were injured in the quake.

The 6.0 magnitude quake late Sunday hit towns in the province of Kunar, near the city of Jalalabad in neighboring Nangarhar province, causing extensive damage.

The quake at 11:47 p.m. was centered 27 kilometers (17 miles) east-northeast of Jalalabad, the U.S. Geological Survey said. It was just 8 kilometers (5 miles) deep. Shallower quakes tend to cause more damage. Several aftershocks followed.

Footage showed rescuers taking injured people on stretchers from collapsed buildings and into helicopters as people frantically dug through rubble with their hands.

Buildings in Afghanistan tend to be low-rise constructions, mostly of concrete and brick, with homes in rural and outlying areas made from mud bricks and wood. Many are poorly built.

One resident in Nurgal district, one of the worst-affected areas in Kunar, said nearly the entire village was destroyed.
