World leaders call for ceasefire in Syria

After urgent negotiations with the Syrian government by the Red Cross and Red Crescent, a handful of ambulances have been allowed into the wreckage of the city of Homs to evacuate 20 women and children and 7 wounded.

The two foreign journalists who have been seriously injured there are refusing to leave until there is a ceasefire.
