As many as 10,000 people are now feared dead following the impact of Typhoon Haiyan in the Philippines.
Many of the dead were located in Tacloban city, with the storm today making landfall in neighbouring Vietnam.
Rescue efforts in the Philippines are being hindered by damage to roads and airports, with hundreds of thousands of people also displaced from their homes.
The storm hit the eastern coastal provinces of Leyte and Samar on Friday.
More than nine million people have been affected in the Philippines.
Many are now struggling without food, shelter or clean drinking water.
A huge international relief effort is now underway, but emergency workers have struggled to reach some towns and villages cut off since the storm.
American military aircraft and ships are being deployed to provide help, with US president Barack Obama issuing a message saying he was “deeply saddened by the loss of life and extensive damage”.
Other countries have also pledged millions of dollars in assistance.

Forecasters predicted a tropical depression would move into the south and central Philippines on Tuesday, potentially bringing heavy rains that would further hamper rescue efforts.
