 “This movement initiates the process of transfer of chemical materials from the Syrian Arab Republic to locations outside its territory for destruction,” said the statement by Sigrid Kaag, the United Nations official responsible for coordinating the effort. He became famous in Saudi Arabia after surviving his own suicide bombing in Iraq in 2004, a bombing arranged by militants with Al Qaeda’s Iraqi branch. The clashes have since become the most serious rebel infighting since the uprising against Assad began in March 2011. One of the most pressing issues in the rebel infighting is the fate of dozens of Syrian and foreign reporters, media activists, aid workers and civilians abducted and held by the al-Qaida fighters since they fanned into the area in March. United Nations agencies that do have some access have also described problems in verifying data.
– Syrian rebels are locked in a bitter and violent struggle—with each other. Hostilities between Syria's more moderate rebel factions and the al-Qaeda-affiliated Islamic State of Iraq and Syria exploded into open warfare on Friday, and it's been so costly that the head of another al-Qaeda affiliate, the al-Nusra Front, is calling for an Islamic court to be set up to settle disagreements, the New York Times reports. Abu Mohammed al-Jolani said the fighting was the result of the "incorrect policies" of the ISIS, but that if there wasn't a ceasefire soon, "the whole battlefield … will pay the price of losing a great jihad." Other rebels accuse the ISIS—which wants to combine Iraq and Syria into one Sunni-ruled country—of hogging resources, applying strict social codes, and kidnapping and killing its foes. So far at least 300 people have died in the rebel in-fighting since Friday, including dozens of civilians, according to the Syrian Observatory for Human Rights, and rebels today captured a hospital-turned-ISIS base in Aleppo, the AP reports. The infighting also highlights a challenge for Saudi Arabia, which is backing the rebels in hopes of ousting Assad's Shiite, Iran-affiliated regime, but is uneasy about the potential for jihadist spill-over, the Times adds.
