Cautious calm engulfed the Ain al-Hilweh Palestinian refugee camp on Tuesday afternoon after an exchange of gunfire between two members of the Fatah Movement left one of them wounded, state-run National News Agency reported. Moein Jabr, a bodyguard for prominent Fatah leader Munir al-Maqdah, was wounded as a personal dispute between him and Fatah member Alaa al-Rifai erupted into gunfire. Radio Voice of Lebanon (93.3) said al-Rifai is loyal to Palestinian Armed Struggle chief Mahmoud Issa, aka al-Lino, who is also a Fatah official. The wounded man was taken to al-Hamshari Hospital in Sidon for treatment, NNA said. The Palestinian follow-up committee conducted the necessary contacts in order to hand al-Rifai over to the relevant Lebanese security authorities, NNA added.
