President Benigno Aquino declares a state of national calamity, as rescue workers in the Philippines struggle to reach remote towns and villages to provide aid to more than 600,000 people.
The Philippine military has been using helicopters to access remote parts of the archipelago, but difficulties remain as much of the country’s infrastructure has been destroyed.
Typhoon Haiyan is estimated to have destroyed 70 to 80 per cent of the structures in its path. Most of the damage and deaths were caused by huge waves that swept away coastal villages in scenes officials likened to the 2004 Indian Ocean tsunami.
Alfred Romualdez, mayor of Tacloban City, where bodies have been piled at the sides of roads and homes have been turned into matchsticks, said aid workers were having trouble sending relief supplies into more remote areas because roads, airports and bridges have been destroyed or covered in wreckage.
The United Nations said officials in Tacloban had reported one mass grave of 300-500 bodies.
The Philippine army is also working to prevent looting, especially in Tacloban, with many survivors having lost everything they own, and are without food.
“The situation is bad, the devastation has been significant. In some cases the devastation has been total,” Secretary to the Cabinet Rene Almendras told a news conference.
In a nationwide broadcast, Mr Aquino said the government was focusing relief and assistance efforts on Samar and Leyte provinces, which acted as “funnels for the storm surges”.
The declaration of a state of national calamity should quicken rescue, relief and rehabilitation efforts.
It will also allow the government to use state funds for relief and rehabilitation and control prices. Mr Aquino said the government had set aside 18.7bn pesos ($432.97m for rehabilitation).
Aid agencies are also concerned about the spread of disease.
United Nations Secretary-General Ban Ki-Moon said in a statement on Sunday: “While many communities are very difficult to reach, with roads, airports and bridges destroyed or blocked with debris, agencies have begun airlifting food, health, shelter, medical and other life-saving supplies and have deployed specialist teams and vital logistics support.”
Unicef has estimated that four million children could be affected by the disaster. Meanwhile, the British government has begun implementing a £6m “rapid response” in the aftermath of the typhoon.
Justine Greening, the international development secretary, said NHS experts have been flown in to Tacloban with shelter kits and water purification facilities.
She told ITV’s Daybreak: “We’ve partnered up with NGOs (non-governmental organisations) that over the next few days will start to get to grips with who is where, but as you can see it is a chaotic situation.
“The first thing is to get the logistic routes open so we can start go get those life-saving supplies to people. We need then to work on the ground to get some semblance of order and start to put families back together.”
Typhoon Haiyan has since made landfall in Vietnam and China, but has now been downgraded to a tropical storm. The wet weather it is brining still presents a risk of flooding and landslides.
