Gaza crisis 'No end in sight' as Israeli strikes hit.
Israel has been shelling Gaza for a fifth day, killing at least 21 people, as PM Benjamin Netanyahu said Israel was ready to "significantly expand" its operation. Rockets from Gaza have again landed in Israel. One rocket caused damage and injuries in the city of Ashkelon. The BBC's Jon Donnison sent this report from Gaza City, where he said there was "no end in sight" as the violence continued. Video by: BBC News
