Police clashed with Palestinian protesters in Jerusalem's Old City, the Gaza Strip and the West Bank on Friday, reflecting growing tensions over an increase in Jewish visits to the Temple Mount.Following the morning prayers at the Temple Mount stone throwing broke out outside of the old city's Damascus Gate, in the east Jerusalem neighborhood Ras al-Amud, near the Rockefeller Museum and near the Church of All Nations, according to Israel Radio.Palestinian militants and youth groups have called for a general uprising in response to the entry by Jewish groups under police escort to the Jerusalem holy site, which is revered by both Muslims and Jews. Police threw stun grenades to disperse small crowds of youths outside Jerusalem's medieval walls, and dozens of protesters marched on a crossing between Israel and the Gaza Strip before being driven back by volleys of tear gas.Earlier on Friday police limited the entrance for Muslim worshipers to the Temple Mount to men over the age of 50 with Israeli IDs and in an attempt to prevent riots.On Tuesday the holy site was closed after police received threats of rioting by Palestinians at the compound. Protests also flared in the West Bank, at a checkpoint outside the northern city of Nablus and in the flashpoint holy city of Hebron, where a Palestinian sniper shot dead an Israeli soldier on Sunday.Witnesses reported several light injuries in the clashes and police said they arrested 12 Palestinians in Jerusalem for throwing stones at security forces. Palestinian protests over a visit to the al-Aqsa mosque compound by then Israeli opposition leader Ariel Sharon in September 2000 spiraled into deadly clashes and a five-year Palestinian uprising, known as the second Intifada.Palestinians oppose Jewish worship at the plaza, which overlooks the Western Wall, seeing it as a first step toward restricting access to the area for Muslims and a deepening of Israeli control over the Old City.Israeli and Palestinian negotiators resumed US-brokered peace talks in late July, ending a three-year stalemate.But friction on the ground has risen during the High Holy Days, with Palestinian leaders complaining about swelling numbers of Jewish visitors, saying some of them try to defy an effective ban on praying on the vast esplanade.Third intifada?"The uprising [in 2000] erupted when al-Aqsa mosque was stormed. They [the Israelis] are now raiding al-Aqsa every day," a senior official with the Islamist Hamas group, Mushir Al-Masri, told thousands of supporters at a Gaza rally."We call upon our people to revolt against tyranny and aggression. Let a third Intifada be declared because this is the best way to teach the aggressors a lesson," he said, adding that "every Jew" would be extracted from Jerusalem. Despite his calls for a revolt, the protests within Hamas-controlled Gaza were low-key. There was also little sign of major confrontation looming in the West Bank, where Palestinian Authority President Mahmoud Abbas exercises partial rule.In a speech at the United Nations on Thursday, Abbas made a public appeal for a halt to the al-Aqsa visits."There must be an end to the near-daily attacks on the religious sites in Occupied Jerusalem, at the forefront of which is al-Aqsa mosque, where the continuation of such attacks will have dire consequences," he said.Allies of Prime Minister Binyamin Netanyahu have been among the most vocal advocates of Jewish prayer at the 35-acre site and the government has done little to stem the flow of visitors to the area.Religious Jews revere the compound as the location of their ancient biblical temples. For Muslims, it is the place where Prophet Mohammed is believed to have ascended into heaven - the third holiest site in Islam.Israel captured the site, along with the rest of east Jerusalem, the West Bank and Gaza Strip, in the 1967 Six Days War. The Jewish state then annexed east Jerusalem as part of its capital in a move never recognized internationally. JPost.com staff contributed to this report.
