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.

In the days since a fragile ceasefire took hold in the Gaza Strip, Israel has launched a major military operation in the occupied West Bank and suspected Jewish settlers have rampaged through two Palestinian towns.

The Israeli military killed at least seven Palestinians in the occupied West Bank on Tuesday as the prime minister announced the start of a “large-scale military operation” in the restive city of Jenin.

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 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.”
