Yemen's President Ali Abdullah Saleh has signed an agreement designed to end months of anti-government unrest. Here is a look at the main provisions in the plan crafted by the Gulf Cooperation Council:

-Mr. Saleh transfers powers to his vice president, Abed Rabbo Mansour Hadi.

-Hadi works with opposition leaders to form a national unity government.

-Hadi calls an early presidential election. Some reports say Mr. Saleh will keep his title until a successor is elected.

-Mr. Saleh receives immunity from prosecution.
