ADDIS ABABA, Ethiopia - African leaders pledged nearly $380 million to help famine-hit families in the Horn of Africa during a donor conference held Thursday.

The African Development Bank announced in a statement a donation of $300 million for long-term development in the Horn of Africa, to be spent by 2013. African nations also pledged $28.8 million in food donations during the conference, held at the African Union headquarters in Ethiopia's capital.

African leaders promised to donate $51 million, the most generous donors being Algeria with $10 million, Egypt with $6 million and Angola with $5 million.

"This is what we pledged today, it is new money and exclusively African," said AU chairman Jean Ping.

African leaders had been criticized for not doing enough to help those affected by the famine. The UN says 12.4 million people need food aid and tens of thousands have died. Aid groups had said they wanted at least $50 million from Thursday's conference.

The Horn of Africa has been suffering from a devastating drought that has been compounded by civil war in Somalia, bad governance and spiraling food prices for months. The UN has said five regions in Somalia are suffering from famine but hunger is also widespread in Ethiopia, Kenya, and Djibouti. No information is available about Eritrea but people there are also believed to be suffering.

Minimal contributions and a slow response had provoked criticism from the donor community.

"It is sad but people have to die before our political leaders take action," said Oxfam Pan Africa director Irungu Houghton.

AU chairman Jean Ping said that Africa's response is not "too little, too late."

He said that in order to be as transparent and accountable as possible, the AU will channel the money through UN agencies.
