David Cameron urges UN efforts on Syria crisis

Prime Minister David Cameron has urged world leaders to do more to stop the "atrocities" of president Bashar Assad's regime in Syria.

In the keynote speech to the United Nations General Assembly, he cited a recent report documenting torture and murder of children by regime forces, saying "The blood of these young children [was] a terrible stain on this United Nations."

Mr Cameron also pledged a further £7.4m ($12m) in UK humanitarian aid for civilians caught up in the civil war in Syria.
