The U.N. says more than 100 people are missing in the rubble of the collapsed U.N. headquarters building in Haiti, including the mission chief.

U.N. peacekeeping chief Alain Le Roy said Wednesday about 10 people have been pulled out, many badly injured and "less than five" are confirmed dead.

French Foreign Minister Bernard Kouchner told French media his country's ambassador reported that everyone in the U.N. building, including mission chief Hedi Annabi, appeared dead. U.N. officials would say only that Annabi is unaccounted for.

Le Roy told reporters an assessment of Haiti's main airport in Port au Prince found it is "fully operational" and planes will arrive Wednesday with aid.

U.N. Secretary-General Ban Ki-moon appealed for aid. He said the United Nations is releasing $10 million from its emergency funds.
