"All of Israel should know, this is a complete loss of control," the mayor said, reports.
What triggered the violence?
Clashes erupted on Friday as Muslims packed the Al-Aqsa mosque to pray during the holy fasting month of Ramadan.
Violence had been building in the Holy City and occupied West Bank for the previous week.
Palestinians hurled stones, bottles and fireworks at Israeli police who fire rubber bullets and stun grenades. The site is sacred to Jews as the location of two biblical-era temples.
More than 220 people, mostly Palestinians, were wounded.
On Saturday, prayers at the mosque compound are held peacefully but violence flares elsewhere in east Jerusalem.
Some 121 Palestinians are wounded overnight, many hit by rubber bullets and stun grenades, the Palestinian Red Crescent says.
Israeli police say 17 of its officers are wounded.
Much of the recent unrest stems from the long-running legal effort by Jewish settler groups to evict several Palestinian families from their homes in the Jerusalem neighbourhood of Sheikh Jarrah.
A lower court ruling earlier this year backing the settlers' decades-old claim infuriated Palestinians.
A Supreme Court hearing on a Palestinian appeal had been set for Monday and risked inflaming tensions further.
On Sunday, the justice ministry delays the hearing in light of "the circumstances".
Scuffles between Palestinians and Israeli police in east Jerusalem continue overnight into Sunday.
In the evening, Israeli police again face off against mostly young Palestinians at several locations in east Jerusalem.
Some 331 Palestinians are wounded, according to the Palestinian Red Crescent, in renewed clashes between Palestinians and police at the mosque on Monday ahead of a planned march to commemorate Israel's capture of Jerusalem in 1967.
"This is unthinkable. Synagogues are being burned. Hundreds of cars set alight. Hundreds of Arab thugs are roaming the streets. Civil war has erupted in Lod."
National Police Commissioner Kobi Shabtai called the events "unprecedented".
While the violence has been widely condemned, there is no sign that either side is willing to back down.
Netanyahu has vowed to expand the offensive, saying "this will take time".
The death toll in Gaza rose to 48 on Wednesday, including 14 children and three women, the Health Ministry said, and more than 300 Palestinians have been injured, including 86 children.
Six Israelis, including three women and a child, were killed by rocket fire, and dozens of people were wounded.
The violence erupted last Friday after weeks of tensions boiled over and Israeli cops clashed with crowds of Palestinians at Jerusalem's Al-Aqsa mosque - on the last Friday of the Muslim holy month of Ramadan.
According to Channel 12 in Israel, Palestinian officials have reached out to their Jewish counterparts in a bid to agree a ceasefire.
Yet Israel has refused with officials saying Hamas has not paid a sufficient price for the rocket attacks, according to reports.
Donald Trump accused President Joe Biden of "weakness" and lack of support for the Jewish state.
"Under Biden, the world is getting more violent and more unstable because Biden's weakness and lack of support for Israel is leading to new attacks on our allies," he said in a statement.
"America must always stand with Israel and make clear that the Palestinians must end the violence, terror, and rocket attacks, and make clear that the US will always strongly support Israel's right to defend itself."
The Biden administration on Tuesday called for calm and restraint by Israel and the Palestinians, urging both sides to avoid "deeply lamentable" civilian deaths.
But "Israel does have a right to defend itself," State Department spokesman Ned Price told reporters.
The Israeli military said 630 missiles were fired from Gaza yesterday with 150 failing to reach Israeli territory.
Some 200 missiles have been intercepted by Tel Aviv's Iron Dome defence system which destroys rockets which are fired towards populated areas.
Israel had sent 80 jets to bomb Gaza and massed tanks on the border as rocket barrages hit Israeli towns.
