A powerful 7.3 magnitude earthquake struck Nepal on Tuesday - the biggest aftershock to date of a quake which left more than 8,000 people dead less than a month ago.
The latest earthquake has left more than 90 people dead and thousands injured.
Meanwhile, search teams are trying to locate a US military helicopter which went missing during an aid mission with six Marines and two Nepali soldiers on board.
Video posted on social media shows "hundreds" of people fleeing from Kathmandu airport following a 7.4 magnitude earthquake.
The quake is the second one of similar magnitude to hit in recent weeks.
