United Nations ? U.N. officials said Tuesday that a small team would return to Baghdad, Iraq, within two weeks, a symbolic move nearly three months after the United Nations withdrew its international staff because of security concerns.

Two security officers and two military advisers will go to Iraq “to provide support to local staff, make security assessments and strengthen the liaison with the coalition,” said a letter from senior U.N. official Kieran Prendergast to U.S. Ambassador John D. Negroponte. The letter asked the U.S.-led coalition for help with the team’s security in Iraq.

The United Nations withdrew its personnel after 22 people were killed when its Baghdad headquarters was bombed Aug. 19.

The latest move does not necessarily mean that the United Nations will return in force right away, a U.N. official said. But the team will be putting the pieces in place for eventual re-engagement, once experts deem the political and physical risks manageable, the official said.
