As the dust settled on Haiti's shattered capital Wednesday, a nightmare scenario emerged: Even the rescuers needed rescuing.

The United Nations said its headquarters in the six-story Christopher Hotel had collapsed Tuesday, killing at least 14 and leaving more than 100 missing.

In addition, the four-star Montana Hotel, where many U.N. personnel were housed, was also badly damaged.

``We know there were 300 people inside the hotel when it collapsed, only around 100 have got out, which greatly concerns us,'' French Secretary of State for Cooperation Alain Joyandet told Agence France-Presse.

Among those lost in the wreckage were the U.N. Mission Chief Hédi Annabi and his deputy Luiz Carlos da Costa.

``Troops have been working through the night to reach those trapped under the rubble,'' U.N. General Secretary Ban Ki-moon said during a press conference Wednesday.

OTHER REPORTS

The online version of Brazil's Folha newspaper said 11 Brazilian peacekeepers had died in the earthquake; and Jordan's government-run Petra news service said three of its peacekeepers had died and 21 were injured.

Alain Le Roy, the under-secretary general for peacekeeping operations, said more than 100 U.N. workers were unaccounted for at the headquarters, and there were an additional 38 members of the U.N. Development Program, who were working from a separate building, who had not been located.

The massive 7.0-magnitude earthquake struck shortly before 5 p.m. Tuesday, toppling thousands of buildings including a hospital, a university, a prison and the National Palace.

Ban said that Annabi was meeting with a Chinese delegation when the earthquake hit.

The U.N. Stabilization Mission in Haiti, or MINUSTAH, has about 3,000 troops and police in and around the capital of Port-au-Prince. Under Annabi's guidance, the peacekeepers had helped train some 10,000 Haitian police, according to U.N. documents.

`WE CAN ADVANCE'

In September, during a U.N. Security Council meeting where the U.N. peacekeeping mission was extended for another year, Annabi said he was optimistic about the country's future. ``If we persevere and stay the course we can advance,'' he said in a press release. ``Haiti enjoys a remarkable opportunity for change.''

PREDICAMENT

Speaking in Port-au-Prince on Wednesday, Haitian Prime Minister Jean-Max Bellerive described the predicament: ``A lot of people that we need to bring help are themselves victims.''
