Jerusalem - Ma'an News- Clashes erupted between Palestinian protesters and Israeli military and police forces across the occupied Palestinian territories on Tuesday morning, following a day of tensions over access to religious sites.

Four Palestinians were injured and nine were detained in the ongoing confrontations.

The violence was centered in occupied East Jerusalem and its environs, namely the Shufat refugee camp, Eisaweyah, Ras Al-Amoud, and Wadi Al-Jouz area of Silwan, as well as the Old City.

Hundreds of young Palestinians attacked a checkpoint at the entrance of the Shufat camp, north of Jerusalem, throwing stones at Israeli forces stationed nearby, Ma'an's Jerusalem correspondent reported.

He said special police forces were called to the scene and fired tear-gas canisters, stun grenades and rubber-coated bullets at the demonstrators. Two young Palestinians were detained, he added.

Israeli forces were seen chasing protesters in Wadi Al-Joz while a helicopter hovered above. Young Palestinians lit fireworks in the Old City as Israeli forces moved in. Three were detained there, among them Iyad At-Tawil, 12, as well as his mother and aunt.

In Qalandiya refugee camp, north of the city, hundreds of students clashed with Israeli forces who fired rubber-coated bullets and stun grenades to disperse the demonstrators. A 15-year-old student was detained there, onlookers said. Clashes also erupted at the Qalandiya checkpoint, an Israeli security official said.

Israeli forces stopped a bus arriving in Jerusalem from Majd Al-Kroom, alleging that the passengers were en route to the demonstrations. They detained a 39-year-old man accused of striking a police officer.

Israeli forces were filmed preventing journalists from covering the events in Eisaweyah, telling a live Al-Jazeera broadcast that the measures were for the reporters' own protection.
