BAGHDAD (AP) — Iraqi President Jalal Talabani has suffered a stroke and was in intensive care at a Baghdad hospital Tuesday, injecting new uncertainty into the country’s political future a year after the U.S. military left.

Although his official powers are limited, Talabani, 79, is respected by many Iraqis as a rare unifying figure seen as able to rise above the ethnic and sectarian rifts that still divide the country. Known for his joking manner and walrus-like moustache, Talabani has been actively involved in trying to mediate an ongoing crisis between Iraq’s central government and the country’s ethnic Kurdish minority, from which he hails.
