U.S. President Joe Biden's national security advisor briefed Israel Prime Minister Benjamin Netanyahu on the "potential" of a normalization deal between Israel and Saudi Arabia after holding talks in the region, the White House said Sunday.

Jake Sullivan also called on the Israeli leader to link the military operation against Hamas in Gaza with a "political strategy" for the future of the Palestinian enclave, it said in a readout of the talks.

In a weekend of high-stakes diplomacy, Sullivan met Saudi Crown Prince Mohammed bin Salman in Dharan on Saturday, before flying directly to Israel for talks with Netanyahu and other key officials.
