U.N. Secretary General Kofi Annan meets Iranian President Mahmoud Ahmadinejad on Sunday after a U.N. official said Tehran would cooperate on a truce between Israel and the Lebanese group Hizbollah. Annan has been touring the region seeking to shore up the ceasefire that halted a 34-day war in Lebanon. His Iran leg of the trip also comes just days after Iran failed to meet a U.N. Security Council deadline to halt sensitive nuclear work. The U.N. chief held talks on Saturday about the Lebanon truce and the nuclear standoff with senior Iranian officials, including Foreign Minister Manouchehr Mottaki. "He (Mottaki) concluded by saying that we can count on his full cooperation" over U.N. resolution 1701, U.N. spokesman Ahmad Fawzi told Reuters after the talks.
