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.

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.

Days into the Gaza ceasefire, the head of Israel's Shin Bet security service has signalled that the country's focus is switching to Palestinian armed groups in the occupied West Bank. Ronen Bar said Israel was in the midst of a multi-front campaign, but that "right now, it's Samaria's [northern West Bank] time".

The city of Jenin, a Palestinian militant stronghold in the Israeli-occupied West Bank, has become a new front for Israel days after it reached a ceasefire deal with Hamas that suspended a 15-month-old war in Gaza.

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

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.

U.S. Secretary of State Marco Rubio spoke with China's Foreign Minister Wang Yi by phone on Friday, China's foreign ministry said, the first call between the two top diplomats since President Donald Trump's administration took office on Monday.

The announcement came shortly after President Trump rescinded Biden-era sanctions on Israeli settlers and Jewish extremists raided Palestinian villages in protest against the cease-fire in Gaza.

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