RAMALLAH (Ma'an) -- Israeli forces on Thursday fired tear gas and stun grenades at journalists covering a sit-in protest outside Ofer prison near Ramallah.

Dozens of protesters held a sit-in outside the detention center to demand the release of prisoners on hunger strike.

Israeli forces ordered the demonstrators to move from the prison's gate, and continued to provoke the protesters even after they moved, a Ma'an correspondent said.

Meanwhile, a heated argument developed between PLO Executive Committee Wasil Abu Yousif and Palestinian National Initiative leader Mustafa Barghouti.

Israeli forces fired stun grenades and tear gas canisters at journalists filming the argument, injuring two Ma'an reporters, a reporter for Sky News and a cameraman for Russia Today.

Soldiers fired a tear-gas canister at a TV van, and injured two Palestine TV journalists.

An Israeli military spokeswoman did not immediately return a call seeking comment.
