Special envoy to Syria, Vatican delegation makes visits
Seeking to forge a solution to Syria's bloody civil war, international envoy Lakhdar Brahimi visited the country's key ally in the region, Iran, before heading Monday to Iraq.
Brahimi met with Iranian President Mahmoud Ahmadinejad and called for an end to the flow of arms to both sides of the conflict, Brahimi's spokesman said.
Rebel fighters have accused Iran of sending advisers to help al-Assad put down the popular uprising.
The Vatican announced on its website that it will send a delegation to Syria next week.
"We cannot simply be spectators to this tragedy that is consuming Syria," said Secretary of State for the Vatican Cardinal Tarcisio Bertone. "The Holy Father has arranged it as such so that a delegation will go to Damascus in the coming days in order to express, on behalf of him and all of us: our fraternal solidarity to the entire population."
