Turkey's Disaster and Emergency Management Authority (AFAD) said there had been 90 aftershocks

The phase of the rescue after the major earthquake struck Turkey and Syria a week ago is “coming to a close” with urgency now switching to shelter, food, schooling and psychosocial care, the UN aid chief Martin Griffiths said during a visit to Syria yesterday.

Thousands of people have been killed in Syria by the earthquake that struck its border region with Turkey on February 6 but aid has been slow to reach the most affected areas.

Aid agencies, both the Turkish and Syrian governments, and the rebel groups must all work together.

Some of the world's most deadly earthquakes in the past two decades are listed below, after a 7.8 magnitude quake struck central Turkey and northwest Syria on Monday and killed hundreds of people.
