Israel’s defense minister has announced a series of raids that he says are targeting “terrorism” in the occupied West Bank, as Palestinian officials warned of a “man-made disaster.”

Israel's defence minister said on Tuesday forces were applying lessons learned in Gaza as a major operation continued in Jenin which the military said was aimed at countering Iranian-backed militant groups in the volatile West Bank city.

As the ceasefire deal between Israel and Hamas takes effect in Gaza, Israel is stepping up its military activity in the West Bank. The Palestinian Health Ministry said six people were killed and 35 injured in a “large military operation” overnight.

Israel’s military is using lessons from the Gaza war in its new West Bank operation to ensure “terrorism does not return,” according to Defense Minister Israel Katz.
