Saudi Arabia ? Following their first official talks in Saudi Arabia, the Iranian and Saudi leaders on Saturday pledged to fight the spread of sectarian strife in the Middle East, which they said was the biggest danger facing the region.

Iranian President Mahmoud Ahmadinejad and King Abdullah also stressed the importance of maintaining Palestinian unity and bringing security to Iraq, the official Saudi Press Agency said.

The agency quoted Ahmadinejad as saying he supported Saudi efforts to calm the situation in Lebanon and end its political crisis. Iran supports Lebanon’s Shiite Hezbollah group, which is trying to topple the U.S.- and Saudi-backed government.

The talks between the two leaders have been touted as a possible means to defuse sectarian tensions in Iraq and Lebanon, and prevent Iran from sliding further into isolation.
