A chair still stands, a building lies in ruins: Haiti's capital, Port-au-Prince, has suffered its worst earthquake in two centuries.
One of the world's poorest states, long wracked by both political unrest and natural disasters, has suffered another devastating blow.
Thousands of people are feared to have died in the disaster. Civilians, as well as UN workers there to help them, were caught without warning.

What rescue services the Haitian capital possesses had difficulty reaching the injured in streets blocked by rubble.
Emergency clinics have been set up to help the injured.

One of the many buildings that collapsed was a children's hospital. Here, people search for survivors amongst the ruins.
Fearing aftershocks, many residents spent the night outdoors. Displaced people gathered in Place Boyer, in the Petionville district of the capital.

Aid agencies say the first priority for those who have survived is food and clean water.
