1,200 Feared Dead in Philippines Typhoon: Red Cross

"This is destruction on a massive scale. There are cars thrown like tumbleweed and the streets are strewn with debris," said Sebastian Rhodes Stampa, the head of a UN disaster assessment coordination team.

"The last time I saw something of this scale was in the aftermath of the Indian Ocean tsunami," he said, referring to the 2004 disaster that claimed about 220,000 lives.

Stampa made his comments after arriving in Tacloban, the destroyed capital of Leyte with a population of about 220,000 people.

More than 100 bodies were littered in and around Tacloban's airport, according to the facility's manager.
