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.

Israel launched a major military operation Tuesday in the occupied West Bank city of Jenin that killed at least nine Palestinians and left at least 40 more people wounded, Palestinian health officials said,

The action came a day after President Donald Trump said he will lift sanctions on ultranationalist Israeli settlers who attacked Palestinian villages.

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.

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.
