Israel took the rare and drastic step of barring Palestinians from Jerusalem's Old City on Sunday as tensions mounted following attacks that killed two Israelis and wounded a child.
The restrictions will be in place for two days, with only Israelis, tourists, residents of the area, business owners and students allowed, police said.
Worship at the sensitive Al-Aqsa mosque compound will be restricted to Old City residents and Arab Israelis, and limited to men aged 50 and above. There will be no age restrictions on women. They will be allowed to enter through one specific gate.
There was no immediate reaction from Palestinian officials.
Saturday's attacks came with Israeli security forces already on alert after recent clashes at the Al-Aqsa compound and surrounding Old City, as well as the murder in the West Bank of a Jewish settler couple.
On Saturday night, a Palestinian said to be an Islamist killed two Israeli men and wounded a woman and a toddler in a knife and gun attack in the Old City. Police shot dead the attacker.
In a separate incident on Saturday, a Palestinian man stabbed a passerby in west Jerusalem before being shot dead by police while he was fleeing the scene. The victim was wounded, police said.
Clashes also broke out overnight around a checkpoint leading to the occupied West Bank involving Palestinians, Israeli settlers and Israeli security forces, with sporadic gunfire heard in the area.
Israeli Prime Minister Benjamin Netanyahu was to return from the United States on Sunday and hold consultations with Defence Minister Moshe Yaalon. His security cabinet is also to meet on Monday, after the end of the Jewish Sukkot holiday, Israeli media reported.
There have been fears that the sporadic violence could spin out of control, with some warning of the risk of a third Palestinian intifada, or uprising.
Last week, in his address to the UN General Assembly, Palestinian president Mahmud Abbas said he was no longer bound by previous accords with Israel, accusing the Israeli government of violating them.
Saturday's Old City attack saw a two-year-old child slightly wounded in the leg and taken to hospital. A woman was in serious condition, rescue services said.
Police spokesman Micky Rosenfeld said it appeared the child had been shot.
The two men who were killed were a 41-year-old rabbi and resident of the Old City as well as a 21-year-old who lives in a West Bank settlement, Israeli media said.
Media reports said three of the victims were members of the same ultra-Orthodox family on their way to pray at the Western Wall.
The attacker first used a knife, but reportedly took a gun from one of the male victims and fired at police when they responded after being alerted, before he was himself shot dead.
Police named him as Mohannad Shafiq Halani, 19, from a village near Ramallah in the West Bank.
Islamic Jihad group said he was one of its members, but did not claim responsibility for the attack. Islamist movement Hamas, in power in the Gaza Strip, praised the attack as "a heroic act of resistance".
The United States condemned it, with State Department spokesman John Kirby saying Washington was "very concerned about mounting tensions in the West Bank and Jerusalem".
Israeli security forces have been on high alert during recent Jewish and Muslim holidays, particularly with Jews visiting the sensitive Al-Aqsa compound, which they call the Temple Mount. The site is located in Israeli-annexed east Jerusalem.
The eight-day Jewish Sukkot holiday began last Sunday and has continued all week.
Thursday night's murder of a Jewish settler couple in the West Bank in front of their four children further fuelled tensions. The Israeli deployed extra troops to the area in a bid to avoid an escalation in violence.
Palestinian police and medical sources said 10 Palestinians were wounded by Israeli fire in the West Bank on Saturday during a raid by troops in Nablus hunting the murderers of the couple.
The Israeli military said that arrests had been made, without providing details.
Thursday night's murders came hours after Netanyahu addressed the UN General Assembly in New York, where he called for a resumption of direct peace talks with the Palestinians.
Abbas addressed the UN a day earlier, issuing his declaration that he was no longer bound by previous accords and pushing for a multilateral peace effort.
