will not go to waste. Their blood was spilled for the freedom of our Palestinian people and for its rights." Netanyahu, speaking at the beginning of the weekly Cabinet meeting Sunday morning, said that "I regret that there are extremists among Israeli Arabs and in neighboring countries who have turned the day on which the State of Israel was established, the day on which the Israeli democracy was established, into a day of incitement, violence and rage. There is no place for this, for denying the existence of the State of Israel. No to extremism and no to violence. The opposite is true Stone-throwing Palestinians .

Uriel Heilman Marcy Oster Dina Kraft Jewish Telegraphic Agency Jerusalem I n the wake of disturbances on Israel's borders that resulted in as many as 14 deaths, Prime Minister Benjamin Netanyahu said in a national address Sunday that he has ordered the Israel Defense Forces to stop the infiltration and defend the country's sovereignty. "This is an appeal against the very exis- tence of the State of Israel, which they call a catastrophe Netanyahu said, responding to massive Arab protests both inside and outside of Israel for Nakba Day — the day Arabs mark as the "catastrophe" of Israel's birth on May 15, 1948. "We hope the calm and quiet will quick- ly return, but let nobody be mistaken, we are determined to defend our borders and sovereignty," Netanyahu said. Hundreds of Arabs from Syria stormed across the border into Israel on Sunday, prompting Israeli troops to respond with live fire killing up to four people, accord- ing to reports. By Sunday evening, most of the infiltrators had been rounded up and returned to Syria. Some of the Syrian infiltrators told Israeli media that they wanted to be grant- ed asylum to live in Israel, calling it safer than living in the current uprising against the Syrian government. Others said they were there to liberate the Golan Heights 36 May 19 c 2011 from Israel. The incident, which marked the first major eruption of violence along the border in decades, came on the same day that an Israeli Arab rammed a truck into pedestrians in Tel Aviv, killing one man and injuring a dozen people. Elsewhere around Israel and the West Bank, thousands of Palestinians protested to mark Nakba Day. The number of Arabs from Syria who breached the border on the Golan Heights was estimated at up to 400. The Israel Defense Forces declared the area of Majdal Shams, a Druze town near Mount Hermon, a closed military zone as Israeli troops tried to round up those who had infil- trated the border. Israeli troops also fired on Palestinian protesters who approached Israel's bor- der with Gaza, wounding several teens, according to reports. Lebanon Protests In Lebanon, thousands of Arabs report- edly converged on Israel's border to dem- onstrate, but they were pushed back when the Lebanese army fired warning shots into the air. Israeli soldiers also reportedly shot in the air and at the feet of Lebanese demonstrators. Up to 10 Lebanese demonstrators were killed in the incident, with most believed to have been killed by the Lebanese army, according to reports. At least 10 Israeli troops were injured in the incidents on the Syrian and Lebanese borders. In Tel Aviv, Israeli law enforcement officials said Sunday morning's truck rampage appeared to be a terrorist attack. The 22-year-old man from the Israeli Arab village of Kafr Kassem who drove into cars and pedestrians on a busy thoroughfare reportedly told police that his tire had exploded, causing him to lose control of his truck. In Jerusalem, Palestinian demonstrators reportedly threw firebombs at Hadassah Hospital on Mount Scopus in Jerusalem. The violence came two days after a Palestinian teen was killed during a pro- test in eastern Jerusalem. The boy may have been shot by a security guard work- ing for several Jewish families who live in the area. Hamas' prime minister in the Gaza Strip, Ismail Haniyeh, told thousands of Muslim worshippers in a mosque Sunday morning that Nakba Day should be observed this year "with great hope of bringing to an end the Zionist project in Palestine:' Haniyeh made the remarks less than a week after his Islamist party and the Fatah Party of Palestinian Authority President Mahmoud Abbas reconciled and announced plans to form a unity govern- ment in the coming weeks. "This is the first year crowds will march to Palestinian borders, annulling the old saying that elderly people die and younger generations forget the past:' Haniyeh told the crowd. In a nationally televised address, Abbas said of the killed protestors, "Their blood West Bank Riots Meanwhile, in the West Bank, clouds of tear gas hovered over hundreds of riot- ing Palestinian youths on the road to Jerusalem. "I want a third intifada," said Ala Barghouti, a 21-year-old accounting stu- dent, his nostrils stuffed with tissues to keep out the sting of the tear gas. "I hope things do escalate today. A third intifada will help move the Palestinian Authority to improve our political situation. "We need more support out here, a stronger presence to get everyone out on the streets',' he said. "We need to get the Palestinian cause back on world radar again:' Energized by the uprisings sweeping the Arab world, a recent unity deal between Fatah and Hamas, and hopes for interna- tional recognition of statehood by the U.N. General Assembly in September, unusu- ally large crowds turned to the streets on Sunday. The West Bank clashes near the Kalandiya refugee camp appeared to be part of a larger effort to overwhelm Israel's borders. In Ramallah, hundreds came together for what was a relatively peaceful gather- ing within the confines of the city, out of view of Israeli troops. A mixed crowd of young and old mingled and spoke of the hopes the so-called Arab Spring has aroused Palestinian society. "All of the nations in the world, and especially the countries in this region, are looking for freedom and independence said Zaki Attari, 45, an employee of the Palestinian Finance Ministry, as he made his way through thick crowds and the sound of drumbeats. Rows of young boys wearing black held black wooden keys symbolic of the homes Palestinian families lost during the fight- ing in 1948, when hundreds of thousands fled or were expelled from their homes. Loudspeakers blared nationalist slogans invoking the Arab Spring. "It's time to be like Egypt. It's time to be like Tunisia. It's time to be like Libya;' said a man leading one of the chants in flag-draped Manara Square in the center of Ramallah. "No more talking; it's time to
