Irasel is bracing for more violence and Palestinian protests after the Hamas militant group called for a "day of rage" Friday.
The last "day of rage" was on Tuesday, sparking four separate attacks on Israelis and clashes between Israeli security and Palestinian youths.
Already overnight in the West Bank, Israeli defense officials say dozens of Palestinians set fire to Joseph's Tomb, a sacred Jewish site.
Palestinian President Mahmoud Abbas condemned the arson attack Friday, calling it "irresponsible," reported French news service Agence France-Presse.
The Al-Aqsa Mosque in Jerusalem has been at the heart of recent violence after rumors Israeli officials wanted to limit access to Palestinians. Israeli security is turning away anyone under the age of 40.
In the last three weeks Palestinians have attacked Jews at least a dozen times, in most cases using knives.
Israelis say they have no other option but to defend themselves.
Jerusalem's mayor has called on Israeli citizens with gun permits to carry their weapons in public.
Outside the mosque Friday morning, groups of young Palestinians who were not allowed in were praying outside.
The Palestinian president has also called for peaceful resistance, but Israelis are bracing for what could be another day of violence.
