Dozens of Palestinian families fled on Monday from the Nur Shams refugee camp in the north of the occupied West Bank, as Israel pushed on with a sweeping military operation."We hear explosions and bombings as well as bulldozers.

More checkpoints started going up between Palestinian cities, slicing up the occupied West Bank and creating choke points the Israeli army can shut off on a whim.

Israeli forces in Nur Shams shot a 23-year-old woman who was eight months pregnant and whose unborn child did not survive, the Palestinian health ministry said.
