U.S. National Security Adviser Jake Sullivan expressed "serious concerns" Sunday to his Israeli counterpart about "violent confrontations" in Jerusalem and planned evictions of Palestinian families from their homes in the city's east, per a White House statement.

Driving the news: More than 250 Palestinians and several Israeli police officers have been wounded since Friday. Israeli police have used tear gas, stun grenades, water cannons and rubber bullets on protesters, who've thrown "rocks and water bottles" at officers, per NPR. The violence continued Sunday night, AP notes.

• Sullivan "encouraged the Israeli government to pursue appropriate measures to ensure calm during Jerusalem Day commemorations" Monday, per the statement — a reference celebrations of Israel's capturing in a 1967 war east Jerusalem, where the Old City is located.
• An annual march by "hardline nationalist Israelis" past holy sites in the area is seen as "provocative," notes AP, which reports "further clashes" are expected Monday.

Of note: Israel's Supreme Court postponed f0r 30 days a hearing Sunday on the possible eviction of several Palestinian families in the Sheikh Jarrah neighborhood of Jerusalem following the unrest.
