Broad agreement over Syria at G8 summit

After two days of talks the G8 summit has drawn to a close in Northern Ireland, with world leaders signing up to a broad agreement on Syria.

They have promised to step up humanitarian aid, and increase diplomatic pressure for peace talks.

But there is no mention of removing President Assad, following Russian opposition.

At a news conference, Russia's President Vladimir Putin warned that arming the Syrian rebels could deliver weapons into the hands of the sort of people who allegedly killed Drummer Lee Rigby in Woolwich.
