Middle East conflict: Palestinians flee Israeli air strikes

In northern Gaza, thousands of Palestinians have been fleeing their homes after Israel warned of more attacks against Palestinian militants.

Palestinian officials say 172 people in Gaza have been killed since the offensive began last Tuesday. Israel says nearly 1,000 rockets have been fired from Gaza in that time.
