John Kerry, US secretary of state, has addressed the media after arriving in Geneva to meet Russian counterpart Sergey Lavrov as the UN tries to forge an international plan to disarm the Syrian government of its chemical weapons.
Lavrov and Kerry will discuss efforts to agree a UN resolution on the issue, as well as the practicalities of finding, removing and destroying chemical stockpiles during a civil war in which more than 100,000 people have already died.
