US Secretary of State John Kerry has described as "constructive," talks with his Russian counterpart Sergei Lav-rov, on securing Syria's chemical weapons. The two men began a second day of talks in Geneva by meeting UN-Arab League envoy Lakh-dar Brah-imi to discuss the wider issue of peace in Syria. Talks between Mr Kerry and Mr Lavrov on the weapons issue began on Thursday and could continue over the weekend. Mr Kerry said they were working hard to find "common ground". The BBC's James Robbins in Geneva says the two powers will work over the next few weeks to try to revive wider peace talks to end Syria's civil war, but until they reach an agreement on the narrower issues of chemical weapons, that feels like a distant prospect.
