President Barack Obama is scheduled to address the United Nations General Assembly in New York two days after the U.S. began airstrikes over Syria to combat the Islamic State and other militant groups in the Middle Eastern country. The gathering scheduled to begin at 9 a.m. Wednesday will also feature speeches from each of the 193 U.N. member states. 

The general debate gives world leaders about 15 minutes to share their priorities with the U.N. Assembly Hall. The speeches are scheduled through Tuesday from 9 a.m. to between 7 p.m. and 9 p.m. each day. In the past, speakers have overstayed their 15 minute invitation, as when former Libyan leader Col. Moammar Gadhafi railed against the international order for 90 minutes in 2009.

Secretary-General Ban Ki-moon was to open the debate and Brazilian President Dilma Rousseff was scheduled to be the first speaker. It's an unwritten U.N. tradition to have a Brazilian delegate speak first and the American delegate second. Other notable delegation speeches scheduled for Wednesday include the Republic of Korea, France, Turkey, Nigeria and the United Kingdom.

For comprehensive information on the general debate of the 69th Session, see the U.N.'s dedicated page here. There are a number of high-level meetings being held throughout the week outside of the General Debate.

The Holy See, the State of Palestine, which are both observer states, will speak along with a European Union delegation.
