Den libanesiske hær åpnet fredag ild for å hindre demonstrerende palestinere å marsjere til flyktningeleiren Nahr el-Bared. To palestinere ble drept og 29 ble såret.
Government soldiers shot at angry Palestinian demonstrators trying to march home to their besieged camp in northern Lebanon on Friday, and two people were reported killed and 29 wounded.
Lebanese youths supported the troops by engaging in fistfights with Palestinian protesters, the state-run National News Agency said.
The confrontation was the first major trouble between Palestinians and Lebanese troops since fighting broke out last month at the Nahr el-Bared refugee camp between the army and Fatah Islam, an extremist group with followers from several Arab nations.
