JERUSALEM (AP) — Hundreds of Israeli ultranationalists gathered Tuesday near Jerusalem's Old City ahead of a contentious march that threatened to spark renewed violence just weeks after a war with Hamas militants in the Gaza Strip.

The planned march in east Jerusalem has posed a test for Israel's fragile new government as well as the tenuous truce that ended last month's 11-day war between Israel and Hamas.

Palestinians consider the march, which usually winds through the Old City's Damascus Gate and into the heart of the Muslim Quarter, to be a provocation. Hamas has called on Palestinians to “resist” the parade, a version of which was held at the height of last month's unrest in the city and helped ignite the 11-day Gaza war.

Hundreds of Jewish nationalists gathered several hundred meters (yards) from Damascus Gate before the early evening march. Most appeared to be young, religious men, and many held blue-and-white Israeli flags. The crowd appeared to be much smaller than during last month's parade.

Ahead of the march, Israeli police cleared the area in front of Damascus Gate, shut down roads to traffic, ordered shops to close and sent away young Palestinian protesters.

Palestinians said six people were arrested, and at five people were hurt in clashes with police.

In the Gaza Strip, Hamas-linked Palestinians launched incendiary balloons into southern Israel, setting a series of fires.

Though there were concerns the march would raise tensions, canceling it would have opened new Prime Minister Naftali Bennett and other right-wing members of the coalition to intense criticism from those who would view it as a capitulation to Hamas. The coalition was sworn in on Sunday and includes parties from across the political spectrum, including a small Arab party.

Mansour Abbas, whose Raam party is the first Arab faction to join an Israeli coalition, said the march was “an attempt to set the region on fire for political aims,” with the intention of undermining the new government.

Abbas said the police and public security minister should have canceled the event. “I call on all sides not to be dragged into an escalation and maintain maximum restraint,” he said.

Police approved a route that will pass by the Damascus Gate, where Palestinian protesters repeatedly clashed with Israeli police over restrictions on public gatherings during the Muslim holy month of Ramadan in April and May.

But the crowd will not pass through the gate into the heart of the Muslim Quarter, a crowded Palestinian neighborhood with narrow streets and alleys. Instead, police said they are to walk around the ancient walls of the Old City and then enter through Jaffa Gate, a main thoroughfare for tourists, head toward the Jewish Quarter and on to the Western Wall, the holiest site where Jews can pray.

Last month's clashes at the Damascus Gate eventually spread to the Al-Aqsa Mosque compound, a flashpoint site sacred to Jews and Muslims. Tensions at the time were further fueled by protests over the threatened eviction of dozens of Palestinian families by Jewish settlers, also in Jerusalem.

At the height of those tensions, on May 10, Israeli ultranationalists held their annual parade, and while it was diverted from the Damascus Gate at the last minute, it was seen by Palestinians as an unwelcome celebration of Israeli control over what they view as their capital. In the name of defending the holy city, Hamas fired long-range rockets at Jerusalem, disrupting the march and sparking the Gaza war, which claimed more than 250 Palestinian lives and killed 13 people in Israel.

Now organizers are again staging the parade, which includes flag waving and the chanting of slogans to celebrate Israel’s capture of east Jerusalem in the 1967 Mideast war. Israel annexed east Jerusalem in a move not recognized by most of the international community and considers the entire city its capital, while the Palestinians want east Jerusalem to be the capital of their future state. The competing claims over east Jerusalem, home to sensitive Jewish, Christian and Muslim holy sites, lie at the heart of the conflict and have sparked many rounds of violence.

Hamas issued a statement calling on Palestinians to show “valiant resistance” to the march. It urged people to gather in the Old City and at the Al-Aqsa Mosque to “rise up in the face of the occupier and resist it by all means to stop its crimes and arrogance.”

Prime Minister Mohammad Shtayyeh, of the internationally backed Palestinian Authority, called the march an “aggression against our people.”

Israeli media reported the military was on heightened alert in the occupied West Bank and along the Gaza frontier in case of violence. Batteries of Israel's Iron Dome rocket-defense system were seen deployed near the southern town of Netivot, near the Gaza border, as a precaution. Hundreds of police will also be deployed.

Meanwhile, the Israel Fire and Rescue Services said it was fighting several blazes apparently caused by the balloons carrying burning rags launched in Gaza toward southern Israeli farmland.

Abu Malek, one of the young men launching the balloons, said called the move “an initial response” to the march.

Defense Minister Benny Gantz met with the military chief of staff, the police commissioner and other senior security officials on Tuesday. He “underscored the need to avoid friction and protect the personal safety of ... Jews and Arabs alike.”

U.N. deputy spokesman Farhan Haq said U.N. officials have urged all sides to avoid “provocations” in order to solidify the informal cease-fire that halted the Gaza war.
