Israel killed two Palestinians in the northern West Bank overnight and into Wednesday, the occupied territory's Heath Ministry said, as the Israeli military focuses on a major crackdown there during the ceasefire in Gaza.

The sudden expansion of Israeli security operations in the West Bank has killed at least 10 people and follows the start of the delicate ceasefire process in Gaza, by which Israeli hostages are released in stages and will also see the gradual withdrawal of Israeli forces.

As Israel withdraws some of its troops from Gaza during a cease-fire there, it has turned attention to another Palestinian territory — in particular a city with a history of militant activity.

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

The United Nations secretary-general has warned that Israel might seize the opportunity to annex the occupied West Bank.

Israel kills two Palestinians in the West Bank as the military focuses on a major crackdown during Gaza ceasefire.

The Israeli military and Hamas said Monday that an air strike killed two fighters from the Palestinian Islamist movement in the occupied West Bank city of Tulkarem. Israel has occupied the West Bank since 1967.
