The Israeli military is expanding its operations in the occupied West Bank and will remain in some refugee camps for the “coming year,” Defense Minister Israel Katz said Sunday.

Israel has ordered its military to prepare for an "extended stay" in parts of the occupied West Bank as it steps up operations against Palestinian militant groups, the Israeli defence minister said on Sunday.

Israel’s defense minister, Israel Katz, said that 40,000 Palestinian residents displaced from militant hotbeds would not be allowed to return to their homes.

Israel said on Sunday its troops would remain for many months in refugee camps in the occupied West Bank, after tens of thousands of Palestinians living there have been displaced by an intensifying military operation.

Israel is deepening its crackdown on the Palestinian territory and has said it is determined to stamp out militancy amid a rise in attacks.

By Raneen Sawafta and James Mackenzie JENIN, West Bank/JERUSALEM (Reuters) -Israel sent tanks into the occupied West Bank for the first time in more than 20 years on Sunday as it ordered the military to prepare for an "extended stay" to fight Palestinian militant groups in the area's refugee camps.

Israeli tanks moved into the occupied West Bank on Sunday for the first time in decades in what Palestinian authorities called a “dangerous escalation,” after the defense minister said troops will remain in parts of the territory for a year and tens of thousands of Palestinians who have fled cannot return.
