Indonesian President Susilo Bambang Yudhoyono here on Thursday called for global cooperation to cope with the Dec. 26 earthquake-tsunami natural disaster which has killed over 90,000 people in his country.

"Many today are in danger of dying of diseases and the death toll must not be allowed to rise any further," the president told the Special ASEAN Leaders' Meeting on Aftermath of Earthquake and Tsunami which opened here Thursday morning.

Susilo said: "Today we confer on the aftermath of natural disaster that left more than 150,000 dead 12 days after the disaster. The death toll in the region keeps rising -- the most destructive disaster in living memory."

He told participants at the meeting that "the eruption of Mount Krakatau killed more than 36,000 people and I remembered in my school days with astonishment...

"My generation face a natural disaster so great and it would inflict human casualties three times that of Krakatau, high toll among children."

Susilo said his government and the world community have responded vigorously with more than 30 countries having contributed to help with fund, logistical resources, food medicineand other assistance.

Despite all tremendous efforts, yet more needs to be done, saidthe president.

"We need to do them very urgently and we need to do them collaboratively."

Susilo said he took a helicopter ride above Aceh and Meulaboh, a distance of about 240 km, to see communities and villages along the coastlines flattened to the ground with no visible signs of life.

"Our response to this unprecedented catastrophe must be equally unprecedented so that it can immediately put an end to the human suffering and misery that came after," he added.
