Israel shells Gaza from sea and air

One missile hit a media tower block in the centre of Gaza City, reportedly injuring six Palestinian journalists.
Israel says it still wants to hit hundreds of Gaza targets as it seeks to stop Hamas and other militant groups from firing rockets into Israel.
Gaza militants on Saturday fired dozens of rockets into Israel, including one at Tel Aviv that was intercepted.
Health officials in Gaza say 48 Palestinians have been killed so far. Three Israelis were killed earlier this week.
At around 02:00 (00:00 GMT) on Sunday, the BBC's Jon Donnison in Gaza City reported hearing more than a dozen shells, apparently fired from Israeli war ships - a new development in Israel's operation Pillar of Defence.
Air strikes were also heard across Gaza City.
