GENEVA — The United Nations says the security situation in Haiti is "stable but potentially volatile" in the wake of last month's earthquake.

The U.N.'s humanitarian office says an armed group attacked a food convoy at the Jeremie airport in the southwest of the country.

It says U.N. peacekeepers fired warning shots and there were no injuries.

The global body says Haitian national police are stepping up patrols to prevent violence and apprehended 33 escaped prisoners on Saturday.

U.N. spokeswoman Elisabeth Byrs said Tuesday several hundred prisoners are still believed to be on the loose after their prisons collapsed in the Jan. 12 quake.

Four U.N. human rights experts also warn of growing risk of Haitian children being abducted, enslaved or trafficked.
