As Abbas prepared to meet Secretary of State John Kerry in Amman for talks focused on rising tensions in annexed east Jerusalem, particularly at the flashpoint Al-Aqsa mosque compound, police clashed with Palestinian demonstrators in the city's Issawiya neighborhood, an AFP correspondent reported.
Around 100 residents, among them schoolchildren, tried to block the main road in protest after police blocked off several of the neighborhood's entrances with concrete blocks.
Police fired tear gas, percussion bombs and rubber bullets to break up the rally.
The meeting between Abbas and Kerry, who arrived in Jordan late yesterday, comes a day after Israel approved plans for another 200 settler homes in a settlement neighborhood of east Jerusalem in a move sharply criticised by Washington.

Much of the unrest in Jerusalem has been fueled by Israeli moves to step up settlement activity in the city and by religious tensions at the Al-Aqsa mosque compound, a site holy to both Muslims and Jews.
Abbas's spokesman said he would tell Kerry of the Palestinians' growing concerns over Israel's actions, particularly in Jerusalem.
"The Palestinian position will be made crystal clear: the Israeli violations are a red line and cannot be tolerated - especially with the tension and Israeli escalation in Al-Aqsa and Jerusalem," Nabil Abu Rudeina told AFP.
"The flagrant disrespect for this holy site and for Palestinian worshippers, marked by daily incursions into the compound... Must be taken seriously by the international community as they are stoking religious sensitivities and aggravating tensions, with the potential to spiral out of control," he said.
Clashes at the mosque compound have drawn sharp criticism from both the Palestinians and Jordan, which has custodial rights at the shrine.
Ahead of Kerry's arrival, King Abdullah met Abbas in Amman for talks in which he expressed his "total rejection" of Israel's "repeated aggressions and provocations in Jerusalem," a palace statement said.
