Israeli police have boosted security and stepped up patrols across Jerusalem to prevent possible clashes when Israelis march through the largely Palestinian east Jerusalem to mark the anniversary of Israel's capture of the area in 1967.
Police spokesman Micky Rosenfeld says 3,000 officers, including border police and undercover units, are on patrol for Jerusalem Day events on Wednesday.
About 30,000 Israelis are expected to march through the largely Palestinian neighborhood of Sheikh Jarrah, past a contentious Jewish enclave there.
Palestinians claim east Jerusalem as the capital of their future state. Israeli Prime Minister Benjamin Netanyahu says Israel will never divide the city.
Rosenfeld says five officers were injured by Palestinians throwing stones and firebombs on Tuesday night.
