UNITED NATIONS -- The U.N. Security Council has decided to reduce the number of U.N. peacekeeping troops and police in Haiti to levels before the January 2010 earthquake devastated the impoverished Caribbean nation.

"The overall security situation, while fragile, has improved," the council's resolution says.

The council backed a recommendation by Secretary-General Ban Ki-moon and voted unanimously Friday to reduce the mission's current authorized military strength of 8,940 to 7,340 troops, and its international police force from 4,391 to 4,241 officers.

The council increased the forces after the earthquake. The resolution adopted by the council said future adjustments should be based on the overall security situation.
