Benjamin Netanyahu has spoken to the father of murdered Palestinian teenager, Mohammad Abu Khdeir, and promised to bring his killers to trial.
Israel's prime minister told Hussein Abu Khdeir his son's killing was "reprehensible" in a statement released by his office on Monday.
"We denounce all brutal behaviour; the murder of your son is is abhorrent and cannot be countenanced by any human being," Netanyahu said, according to the statement.
Those responsible for the death would be "dealt with to the fullest extent of the law", he added.
Earlier, Israeli police arrested six people in connection with the death of Abu Khdeir, who Palestinians say was killed in revenge for the murder of three settlers last month.
Officials said the suspects, who included several minors, are from Jerusalem, Beit Shemesh, and Adam, an illegal settlement in the West Bank near Jerusalem.
Abu Khdeir was on his way to morning prayers in East Jerusalem when he was abducted and burned alive, according to the Palestinian Authority's attorney general.
His killing led to violent clashes between Palestinian youths and Israeli police in several areas of the city, which left more than 100 people injured.
In the same incident, Israeli security forces were caught beating Mohammad's cousin, US citizen Tariq Abu Khdeir, in a case that prompted further outrage and condemnation from the US.
Tariq Abu Khdeir was arrested and released on bail by an Israeli court on Sunday.
