Tens of thousands flee Khan Younis amid evacuation order

Tens of thousands of Palestinians have been fleeing the southern city of Khan Younis. The Israeli military has issued an evacuation order, telling civilians to immediately leave a wide sweep of land to the east of the city. The evacuation instructions are being taken as a sign troops are likely to launch a new ground assault. Correspondent in Tel Aviv, Sarah Coates, spoke to Corin Dann.
