NEW YORK — President Barack Obama opens two days of meetings at the United Nations by seeking to boost Libya's transitional leadership.

Obama will also tout the early success of the international community's efforts to end Moammar Gadhafi's rule.

The president will meet with the chairman of Libya's National Transitional Council Tuesday morning. He'll also convene a larger heads of state meeting to discuss the next phase of Libya's transition.

Obama will also hold meetings Tuesday with Afghan President Hamid Karzai. It's the first in-person meeting for the two leaders since Obama announced plans to withdraw more than 30,000 U.S. troops from Afghanistan by the end of next summer.

Obama's attempts to point out progress in Libya threaten to be overshadowed by a showdown over Palestinian statehood.
