Death toll more than 15,000 ( From CNN)

YANGON, Myanmar (CNN) -- The death toll from the Myanmar cyclone is more than 15,000 people, Myanmar's government has said, with at least 10,000 killed in the township of Bogalay alone, according to the Chinese state-run news agency Xinhua.

The government of neighboring Thailand said Myanmar's leaders had already requested food, medical supplies and construction equipment, AP reported. The first plane-load of supplies was due to arrive Tuesday, a Thai spokesman said.

United Nations Secretary-General Ban Ki-moon said in a statement he was "deeply saddened by the loss of life and the destruction suffered by the people of Myanmar" and pledged to mobilize international aid and assistance as needed.

A United Nations Disaster Assessment and Coordination team is on stand-by to assist the government in responding to humanitarian needs if required, the statement said.
