Palestinian security forces fired at protesters who attacked a Gaza police station with rocks and pipe bombs, demanding the execution of a suspected collaborator with Israel being held inside, witnesses said.
Hospital officials said 21 people, including seven policemen, were wounded in the violence in Rafah refugee camp in the southern Gaza Strip.
The crowd of 500 called for the death of a Palestinian suspected of having helped Israel kill four militants from the fundamentalist Islamic group Hamas in the Gaza Strip in a recent attack in which two civilians also died.
Police and members of the Preventive Security service opened fire after protesters threw rocks and at least 10 pipe bombs at the police station, witnesses said.
A Palestinian security official accused local Hamas activists of inciting the crowd.
"The suspect is still under interrogation and if convicted he will be brought to trial, the official said.
The Palestinian Authority has previously executed two men accused of collaboration with Israel. Several others were shot dead by Palestinian armed activists.
