Haiti earthquake
The earthquake has left tens of thousands of people dead, and rescuers are continuing an increasingly desperate search for survivors.
The US has already sent an aircraft carrier, the USS Carl Vinson, to Haiti and the USS Bataan, carrying a marine expeditionary unit, is on its way.
A hospital ship and more helicopters are due to be sent in the coming days, carrying more troops and marines, with the total number of US troops to rise to between 9,000 and 10,000. Aid groups say it is a race against time to find trapped survivors.
Plane-loads of rescuers and relief supplies are arriving from the UK, China, the EU, Canada, Russia and Latin American nations.
The Pan American Health Organization has estimated that the death toll could be as high as 100,000, while the UN said about 300,000 had been made homeless.
