All West Bank land crossings will be closed during Tuesday's election in Israel, the country's military says, and Palestinian workers will be barred from entering all settlements.
The restrictions come amid a crackdown in the occupied West Bank after Palestinian gunmen killed two Israeli soldiers in the territory.
The Israel Defense Forces announced a "ban on the entry and exit of Palestinian workers throughout Judea and Samaria and the Jordan Valley, including industrial zones, as well as the closure of all land crossings" on Tuesday.
It said most workers would also be barred from settlements from Sunday, with the exception of industrial zones and a limited number of other areas.
Before the Hamas-led October 7, 2023 attack on Israel, more than 100,000 Palestinian workers were permitted to enter Israel. Since then only a small fraction have had their permits restored.
Prime Minister Benjamin Netanyahu announced a major operation on Friday in response to the killing of two Israeli soldiers by two Palestinian gunmen in an attack on a checkpoint. Three other Israeli soldiers were injured, and the gunmen were also killed.
The Israeli military have been demolishing homes and businesses in the city of Hebron, with hundreds of families having been displaced.
Israeli Defence Minister Israel Katz said about 2,000 residents had been displaced by the operation, which has led to at least one whole street appearing to have been flattened, according to footage shared online.
Even before the entry and exit bans on workers were announced by the IDF on Sunday, the military had cordoned off the city, heavily restricting the movement of its 200,000 residents.
It is common for Israeli forces to demolish the homes of Palestinians who are suspected of carrying out attacks on Israelis in the West Bank - a practice Israeli rights groups have criticised as collective punishment.
Friday's shooting came during a tense time for the region, just days ahead of Israel's election taking place on Tuesday.
In an interview with Israel's i24 television channel released on Saturday, Netanyahu threatened a "very big surprise" for the Palestinian Authority (PA), which governs parts of the territory.
Hebron Mayor Youssef al-Jaabari said the operation was being "driven by the elections" and that Netanyahu and his ministers were attempting to secure the votes of the far right and the settlers.
On Saturday, thousands gathered in Tel Aviv for a large anti-government demonstration.
The protest was organised by the October Council, a group founded by the families of victims and hostages taken by militants on 7 October 2023, to demand accountability for the failure to prevent the Hamas-led attack.
"Three days before the election, we will hold the culminating event marking three years of struggle to uncover the truth, demand accountability, and establish a state commission of inquiry," the October Council wrote on X ahead of the rally.
The gathering saw the participation of the leaders of the four main opposition parties, including Gadi Eisenkot, the former military chief of staff who is neck and neck with Netanyahu.
