Palestinian youth 'burned to death'
An Arab teenager who Palestinians say was killed in a revenge attack was burned to death, officials said a post-mortem examination showed.
Meanwhile Palestinian militants fired two rockets towards a major southern city deeper into Israel than any other attack in the current round of violence.
The Israeli military said its Iron Dome defence system intercepted the rockets that were aimed at Beersheba. The military also said at least 29 other rockets and mortars were fired from the Gaza Strip at Israel over the weekend. It said it had retaliated with airstrikes on militant sites in Gaza.
Clashes between Israeli police and Palestinian protesters spread early on Saturday from Jerusalem to Arab towns in northern Israel as hundreds of people took to the streets and threw rocks and fire bombs at officers who responded with tear gas and stun grenades, police said.
Palestinian attorney general Abdelghani al-Owaiwi said he received initial post-mortem examination results from a Palestinian doctor who was present at the test in Tel Aviv.
He said it shows that 16-year-old Palestinian Mohammed Abu Khdeir, whose death has sparked large protests in his east Jerusalem neighbourhood, suffered burns on "90% of his body".
"The results show he was breathing while on fire and died from burns and their consequences," Mr al-Owaiwi said.
His account provided the first details of the preliminary findings to be made public. The Israeli health ministry could not be reached for comment.
The post-mortem exam found evidence that Abu Khdeir had breathed in the flames as burns were found inside his body, in his lungs, bronchial tubes and his throat, Mr al-Owaiwi said.
He also said the young man had suffered wounds on the right side of his head apparently from impact with a rock or another hard object.
Abu Khdeir's charred body was found in a forest on Wednesday after he was seized near his home.
Palestinians immediately accused Israeli extremists of killing him to avenge the deaths of three Israeli teenagers who had been abducted and killed in the West Bank. Israeli police said an investigation is still under way and they have not yet determined who killed the boy or why.
Israeli leaders have widely condemned the killing of the Palestinian youth, and prime minister Benjamin Netanyahu vowed those responsible would be brought to justice.
Palestinians took to the streets in protests after news of the boy's death on Wednesday and clashed with police in east Jerusalem. Riots erupted in east Jerusalem on Friday as thousands of Palestinians massed for the boy's burial.
Near the town of Qalansawe, protesters also pulled over a car driven by an Israeli Jew on Saturday, pulled him out and set the vehicle on fire, police spokeswoman Luba Samri said. The driver was not injured. Several other Israeli cars were also torched, she said. Dozens of protesters were arrested across the country throughout the day.
Protests subsided by noon but resumed in the evening with violent demonstrations in several Arab towns in the north of the country, police said.
Israel's public security minister, Yitzhak Aharonovitch, visited areas of friction and said police would display "zero tolerance" towards those "who take the law into their own hands and harm innocent people".
Israeli Arabs, unlike Palestinians in the West Bank and Gaza Strip, hold citizenship rights. But they often face discrimination and mostly identify with the Palestinians. Even so, violent riots like these are rare.
Palestinian protesters in Jerusalem also used an electric saw to damage the light rail that connects the heavily Arab populated eastern sector of the city with the mostly Jewish West, Ms Samri said.
President Shimon Peres spoke with Arab leaders on Saturday night in Israel urging calm. "We must unite to prevent tragedies and loss of life. Together we can lower the flames and protect the innocent people," he said.
The chaos began after three Israeli teenagers, one of whom was a US citizen, were abducted in the West Bank on June 12, sparking a huge manhunt that ended with the gruesome discovery of their bodies earlier this week.
In a separate incident, relatives told the Associated Press that Abu Khdeir's 15-year-old cousin Tariq, a US citizen who goes to school in Florida, was beaten by police during clashes on Thursday ahead of the funeral. The US consulate had no immediate comment on the report.
The Florida chapter of the Council on American-Islamic Relations called on the US department of state to demand that Israel immediately release Khdeir.
His parents, Suha and Salah, said Tariq was detained but had been treated at an Israeli hospital. They released photos showing his face swollen and badly bruised.
Ms Samri, the Israeli police spokeswoman, said that Tariq Abu Khdeir had resisted arrest and attacked police officers. He was detained with a slingshot in his possession used to hurl stones at police, along with six other protesters, including some armed with knives, she said, adding that several officers were hurt in that specific protest, one of many that day.
Tariq's father said he witnessed his son's arrest and insisted the boy was not involved in the violence.
Amateur video of what he said was the beating aired on a local television station, and he said he could recognise his son from his clothing.
The channel that aired it, Palestine Today, is funded by Iranian-backed Islamic Jihad, a militant group that has carried out suicide bombings and other attacks aimed at civilians.
Other footage shows uniformed men dragging someone on the ground.
The face of the person cannot be seen in either video, and the circumstances leading up to the beating are not shown.
Israel's justice ministry said an investigation had been opened over the footage.
The rocket fire on Beersheba on Saturday was the first since 2012, which came during intense fighting between Israel and Gaza militants.
Israel launched a massive crackdown on the Islamic militant group Hamas after the abduction of the Israeli teenagers, while retaliatory Palestinian rocket attacks and Israeli airstrikes intensified. The military says Palestinian militants have fired more than 150 rockets at southern Israel, and it has responded with airstrikes on more than 70 targets in Gaza.
