Israel’s far-right national security minister put the already-fragile Gaza cease-fire talks at risk by visiting Jerusalem’s most sensitive holy site on Thursday morning.

Itamar Ben-Gvir, an ultranationalist settler leader, said he had gone up to the contested Jerusalem hilltop compound of Al-Aqsa Mosque to pray for the return of the hostages ″but without a reckless deal."

Ben-Gvir said he was pressuring Netanyahu not to give in to international pressure and to continue with the military campaign in Gaza.

The move threatens to disrupt sensitive talks aimed at reaching a cease-fire in the nine-month-old Israeli war on the Gaza Strip. Israeli negotiators landed in Cairo on Wednesday to continue talks.

Ben-Gvir's visit also came just days before Prime Minister Benjamin Netanyahu leaves for a trip to the United States, where he will address Congress. Ben-Gvir last visited the site in May, to protest countries unilaterally recognizing Palestinian statehood.

Jews and Muslims both claim the Jerusalem hilltop compound, which is considered the holiest site for Jews and the third holiest for Muslims after Mecca and Medina in Saudi Arabia.

Palestinians consider the mosque a national symbol and view such visits as provocative. However, Ben-Gvir has frequently visited the site, revered by Jews as the Temple Mount, during tense periods. Tensions over the compound have fueled past rounds of violence.
