Diplomatic front: Special envoy to Syria visits Iran and Iraq
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 Syrian President Bashar al-Assad put down the popular uprising.
Before Brahimi departed Iran, Foreign Minister Ali Akbar Salehi handed him a "written and unofficial proposal" for resolving the Syrian crisis, Iran's IRNA news agency reported Monday. Details of the plan were not publicized.
In Baghdad, Brahimi met with Prime Minister Nuri al-Maliki. "Iraq fully supports the joint U.N. and Arab efforts in order to reach a political solution to the deepening crisis in Syria," al-Maliki said in a statement issued by his office.
Brahimi, the U.N.-Arab League joint special envoy to Syria, is visiting key countries in the region, including Egypt and Saudi Arabia. Over the weekend, he met in Istanbul with Turkish officials and with Syrian opposition leaders in an effort to broker a cease-fire.
Turkish Prime Minister Recep Tayyip Erdogan has repeatedly denounced al-Assad, accusing him of massacring his own people and calling for his resignation.
Turkey is hosting about 100,000 Syrian refugees, and cross-border shelling that killed five Turkish civilians has led to a heightened confrontation between the two neighbors.
Syria has berated its former ally, accusing Turkey of arming and funding Syrian rebels. CNN journalists have witnessed assault rifles, rocket-propelled grenades and machine guns being taken from Turkey to rebels inside Syria.
The violence is showing no sign of abating. On Monday, 100 people were killed nationwide, the opposition Local Coordination Committees in Syria said, including 34 in and around Damascus and 29 in Aleppo.
The World Health Organization condemned attacks on health facilities in Syria, saying they have damaged such facilities across the country, "limiting access and the provision of essential health services."
It added, "almost 67% of public hospitals have been affected as a result of the conflict and 29% of those affected are out of service."
The opposition says more than 30,000 people have been killed since March 2011, when anti-government protesters took to the streets calling for political reform and an end to four decades of Assad family rule. The government responded with a violent clampdown, spawning an armed conflict that has spiraled into a civil war.
CNN cannot independently confirm reports of casualties in Syria because the government has restricted access by international journalists.
