A Palestinian disguised as a photojournalist stabbed an Israeli soldier in Hebron Friday, amid a "day of rage" that began with Palestinians torching a site believed to be the tomb of the biblical figure Joseph.

Israeli troops shot and killed the stabber. Three more Palestinians were killed by Israeli fire in clashes between stone-throwers and Israeli troops in several West Bank towns and on the Israel-Gaza border, Palestinian medics said.

The latest round of violence and bloodshed came as the United Nations Security Council held an emergency meeting on the fighting. Speaking before the meeting, new Israeli Ambassador Danny Danon displayed a Palestinian diagram meant to incite violence, entitled: "How to stab a Jew."

He blamed the Palestinian government and media for provoking attacks among children and teenagers. “You can see with this picture what incitement looks like,” he added.

The Palestinian ambassador to the United Nations, Riyad Mansour, blamed what he called Israeli "terror" through its occupation of East Jerusalem. He said such actions "will not break the will of our people."

Speaking at the White House, President Obama called on both sides to control their rhetoric. He added, "The atmosphere in which there’s so much tension... creates the potential for more misunderstandings and triggers."

In Friday's stabbing, a Palestinian man wearing a T-shirt with the word "press" in large letters wounded the Israeli soldier before troops shot and killed the attacker.

At one point, shouts were heard, followed by several gunshots. Troops rushed to the scene of the stabbing, near a military jeep, and administered aid to the injured soldier who was eventually taken away by ambulance. The attacker lay on the ground, clutching a knife in his right hand.

The incident heightened concerns among journalists about their safety. The Foreign Press Association for Israel and the Palestinian territories said it "marks a worrying development" that demands all media operate with greater caution.

"We utterly deplore this violation of press privilege and call on local Palestinian media organizations to immediately verify all media credentials," the FPA said in a statement.

The attacker's name has not been released, but local journalists said they did not know him.

In Nablus, another West Bank city, Palestinians firebombed the tomb, an attack condemned as "irresponsible" by Palestinian President Mahmoud Abbas. Flames blackened exterior walls of the small stone structure, a scene of Israeli-Palestinian clashes in the past.

Confrontations also erupted in the biblical town of Bethlehem and the Israel-Gaza border.

In Gaza, hundreds approached a border crossing with Israel, throwing stones and drawing Israeli fire that killed one Palestinian and wounded two, health officials said. In Bethlehem, dozens of Palestinians hurled stones and firebombs at Israeli troops who responded with tear gas, rubber-coated steel pellets and live rounds.

In the past month, eight Israelis were killed in Palestinian attacks, most of them stabbings. During the same period, 36 Palestinians were killed by Israeli fire -- 15 labeled by Israel as attackers, and the others in clashes between stone-throwers and Israeli troops.

Many of the Palestinian assailants are from east Jerusalem, the sector of the city captured by Israel in 1967 and sought by the Palestinians as a future capital. The recent attacks have largely been carried out by individuals with no ties to militant groups. The violence comes at a time when a possible partition of the land between the Jordan River and the Mediterranean into two states -- Palestine alongside Israel -- is fading fast.

In response to the stabbings, Israel has taken unprecedented measures, including setting up checkpoints in Arab neighborhoods of Jerusalem this week despite Israel's long-standing assertion that the city is united.

In one area, men passing through a checkpoint Friday said they lined up and ordered by troops to lift their hands and shirts to show they were unarmed before being allowed to pass.

Israel also imposed restrictions on Muslim worship at the Al-Aqsa Mosque compound, Islam's third holiest site in Jerusalem's walled Old City. Men under 40 were barred from the shrine, and hundreds of young worshippers spread out prayer mats on streets leading to the Old City.

The Muslim-run shrine, also revered by Jews as the holiest site of their religion, has been at the root of recent tensions. Palestinian and Muslim leaders have alleged Israel is attempting to change long-standing arrangements that bar Jews from praying on the hilltop compound, a claim denied by Israeli Prime Minister Benjamin Netanyahu. However, several senior members of Netanyahu's coalition have called for Jewish prayer rights at the site, once home to biblical Jewish Temples.

The widespread perception among Palestinians that Al-Aqsa is under threat from Israel has fomented tensions and violence.

Abbas has tried to lower the temperature, telling his security commanders that armed attacks on Israelis counter Palestinian interests. However, he has also told his security forces not to stop Palestinian stone-throwers heading to confrontations with Israeli troops.

Abbas on Friday condemned the Nablus arson as "irresponsible," ordered an investigation into who was behind it and said repairs would begin immediately, according to the official Palestinian news agency WAFA.

Dore Gold, a senior Israeli Foreign Ministry official, said the site was targeted "just because it is a place in which Jews pray." Lt. Col. Peter Lerner, an Israeli army spokesman, said the attack violates freedom of worship and that the military will "bring the perpetrators of this despicable act to justice."

For centuries, the site has been identified with the biblical Joseph but some Palestinians say it was a sheikh's grave or used as a mosque. The tomb has become a popular prayer site in recent years among some sects of religious Jews.

The site is located in an area under Palestinian self-rule and visits by Jews are coordinated between Palestinian security forces and Israeli troops.
