French Foreign Minister Laurent Fabius said on Saturday that all indications show that Syria was behind a \"chemical massacre\" near Damascus that the opposition claims killed hundreds. \"All the information at our disposal converge to indicate that there was a chemical massacre near Damascus and that the Bashar regime is responsible,\" Fabius said on a visit to Ramallah in the West Bank. The government of Syrian President Bashar al-Assad denies it unleashed chemical weapons on Wednesday near Damascus despite claims by the opposition which says 1,300 people were killed in the alleged attacks.
