Former Israeli Ambassador to the U.S. Michael Oren discusses the latest in the fight against Hamas, the possibility of a two-front war and concerns for civilian casualties.
Israeli tanks battled their way to the centre of Khan Younis on Sunday in a major new push into the heart of the main city in the southern Gaza Strip which is sheltering hundreds of thousands of civilians who fled other parts of the enclave.
Residents said tanks had reached the main north-south road through the middle of Khan Younis after intense combat through the night that had slowed the Israeli advance from the east. Warplanes were pounding the area west of the assault.
