Annan cited the earthquake in Bam, Iran, that killed about 30,000 people in December 2003. Iranian officials complain that only a tiny fraction of the more than $1 billion promised has been sent.

Some countries were already pleading for additional attention.

At least 50,000 people in Somalia urgently need food, water, shelter and medical care a week after deadly tsunamis slammed African shores, officials told the Associated Press on Monday.

Some 24 countries, including the United States, have pledged to send relief supplies to Somalia, but nothing has arrived on the ground, said Somali presidential spokesman Yusuf Mohamed Ismail. He said survivors urgently need help after losing their homes and livelihoods.

"We are very happy that relief supplies have arrived in Asia, which was hit the hardest by the tragedy," Yusuf told the Associated Press. "But Somalia — which has been ravaged from a 13-year civil war, drought and political neglect — also needs emergency help to deal with the latest calamity."
