sraeli PM Benjamin Netanyahu has promised to bring to justice the killers of a Palestinian teenager whose death has sparked days of rioting.
He was speaking after Israeli police arrested six Jewish suspects over the killing of Mohammed Abu Khdair in Jerusalem on Wednesday.
Police believe there was a nationalist motive to the killing, which followed the murder of three Israeli teenagers.
Meanwhile, Israeli air strikes on the Gaza Strip have killed six people.
One strike on Sunday evening – reportedly from a drone – left two people dead and came at the end of a day that saw at least 20 rockets fired from Gaza into Israel.
Two later Israeli strikes on Gaza left another four people dead. All six were described as Hamas militants, in what the movement called the biggest single hit against the Islamist group since 2012.
Anger and grief
There have been days of tit-for-tat strikes across the Gaza border.
Tensions between Israel and the Palestinians have risen in an outpouring of anger and grief over the deaths of the four teenagers.
The funeral of Mohammed Abu Khdair in East Jerusalem on Friday triggered repeated clashes between police and Palestinian youths there and in Arab-Israeli towns in the north of Israel.
Earlier in the week, the three Israeli teenagers Naftali Frenkel, Gilad Shaer – both 16 years old – and Eyal Yifrach, 19 were buried. They were abducted while hitch-hiking in the West Bank and their bodies were found last Monday.
“We will not allow extremists, it doesn’t matter from which side, to inflame the region and cause bloodshed,” Mr Netanyahu said in a televised statement, after the suspects in the Khdair killing had been arrested.
“Murder is murder, incitement is incitement, and we will respond aggressively to both.”
Justice Minister Tzipi Livni said her department was investigating some of the anti-Arab incitement seen on social media last week.
“These things need to be cut when they are small,” she told Channel 2 TV. “At this moment, everybody’s job should be to lower the flames.”
Israeli cabinet minister Jacob Peri, a former head of the Shin Bet security agency, said he had met Arab leaders in northern Israel to calm tensions.
President Shimon Peres is also said to have been in contact with Arab leaders.
sraeli officials said the six suspects remained in custody and were being interrogated.
They were described as young males, including some minors, all of whom live in the Jerusalem area.
About 50 people have been arrested in protests following Mohammed Abu Khdair’s death, officials say.
Among them was the victim’s 15-year-old cousin – a US citizen – whose family says he was beaten by Israeli security forces.
The US State Department said it was “profoundly troubled” by the reports and Israel’s justice ministry has launched an investigation.
The boy, Tariq Khdair, who attends a school in Florida, was bailed after appearing in court on Sunday, accused of attacking police officers during the unrest.
His parents deny that he was involved in the riots.
Mohammad Abu Khdair was abducted on Wednesday morning and found dead hours later. He had reportedly been burnt to death.
