On Tuesday, an Arab gunman killed at least five people in a Tel Aviv suburb before being fatally shot, according to the national ambulance service. It was Israel's third deadly attack in a week.
"Israel is confronted by a wave of murderous Arab terror," Prime Minister Naftali Bennett tweeted following the shootings in Bnei Brak, a Jewish ultra-Orthodox city on the outskirts of the commercial capital of Israel.
The shooting brought the total number of people killed by Arab gunmen in Israel over the last week to 11, the highest level in years.
Palestinians have reported increased settler violence throughout the West Bank and East Jerusalem, which Israel captured in the 1967 war.
A man dressed in black and brandishing an assault rifle was seen on an amateur video broadcast on Israeli television stations walking down a road in Bnei Brak.
According to Israeli media reports citing unidentified security officials, the assailant was a Palestinian from a village near the occupied West Bank city of Jenin.
According to police, he murdered four civilians and an officer who arrived on the scene before officers shot and killed the gunman.
The attack elicited no immediate claim of responsibility.
Last Ramadan, Palestinians clashed nightly with Israeli police and settlers. Raids on the Al-Aqsa mosque compound and a ban on evening gatherings at Damascus Gate contributed to the escalation of violence between Israel and Gaza militants, which resulted in 11 days of Palestinian rocket attacks and Israeli airstrikes.
In Bnei Brak, witnesses reported that the gunman initially targeted apartment balconies before moving to people on the street and in a car.
"I live on Hashneim Street in Bnei Brak and was home when I heard gunshots," paramedic Menachem Englander told Magen David Adom in a tweet. "I rushed out into the street and saw a terrorist brandishing a weapon at me. By some miracle, his weapon jammed and he was unable to fire."
Last week, an Arab citizen of Israel stabbed and rammed four people in the southern city of Beersheba before being shot dead by a passerby. Israeli authorities stated that he was a supporter of the Islamic State.
While an Israeli-Arab summit took place in southern Israel on Sunday, an Arab assailant shot and killed two police officers in Hadera, a city about 50 kilometers (30 miles) north of Tel Aviv. He was shot and killed by other officers.
Islamic State militants claimed responsibility for the attack in Hadera.
