The United Nations says the damage caused by typhoon Haiyan in the Philippines will require a huge international response. The UN says that the local officials estimated that the storm killed 10,000 people in a single city Tacloban. Nick Bryant reports from the UN in New York.
The destruction from the typhoon is massive and unprecedented according to the UN humanitarian officials who are helping to coordinate the relief. Almost 10 million people have been affected and 660,000 displaced from their flattened communities. The UN has described the response in the Philippines government as very impressive, but clearly much more needs to be done on the ground. Response teams have focused on providing purified water, food, shelter and medical support for the survivors, while an urgent priority is to bury dead bodies because of the risk of spreading disease. But the relief effort is being hampered by the damage to roads and local infrastructure.
Our correspondent Jonathan Head is at the airport in Tacloban. He explained how the damage was affecting efforts to help survivors.
This airport is effectively cut off from the city. It's taking people more than an hour to get the between the two. So even assistances are brought in here, they can't get out. And of course there are towns and villages further afield from Tacloban. But it's still completely isolated. It has not receive anything at all, because it's still a very preliminary aid effort.
