Chemical weapons experts have determined that mustard gas was used in a Syrian town where Islamic State insurgents were battling another rebel group, according to a report by an international watchdog seen by Reuters.
Evidence now suggests that a bomb planted by the Islamic State militant group is the likely cause of last weekend's crash of a Russian airliner over Egypt's Sinai peninsula, U.S. and European security sources said on Wednesday.
President Barack Obama said on Monday the planned deployment of dozens of U.S. special forces to Syria to advise opposition forces fighting Islamic State did not break his promise not to put "boots on the ground" in the Syrian conflict.
The first bodies from a plane crash in Egypt in which all 224 passengers, most of them Russians, died over the weekend arrived in St Petersburg early on Monday morning aboard a Russian government plane.
