Barack Obama, the US president, has given a televised speech in response to Haiti's catastrophic earthquake, pledging $100m of aid to the stricken island.

Victims have spent their second day amongst the battered landscape, with legions of people confirmed dead and thousands more feared trapped under rubble.

The Red Cross in Haiti fears up to 50,000 people were killed in Tuesday's earthquake, but Haitian officials say it could be twice that.
