[Ma'an] A hand grenade reportedly exploded at the office of Fatah official Sultan Abu Al-Aynayn in the city of Tyre, Lebanon on Monday. A correspondent for the Beirut-based news site NOW Lebanon said no injuries were reported, but that the explosion caused property damage in the Rashdiyeh refugee camp in south Lebanon. The reported attack comes after Aynayn accused external parties of bringing foreign fighters linked to Al-Qaeda into the Palestinian refugee camps in Lebanon
"We have taken measures to prevent Al-Qaeda from infiltrating Palestinian refugee camps after we received information that external parties were seeking to export extremists, particularly from Iraq," Abu al-Aynayn said in an interview with AFP.
Earlier on Sunday Fatah gunmen clashed with fighters affiliated with the Jund Ash-Sham faction in Ein Al-Hilweh refugee camp in the city of Sidon. Lebanon's Naharnet website reported that one person was wounded in the half-hour skirmish.
The incident came one month after the Fatah movement's leader, President Mahmoud Abbas, visited Beirut for talks with Lebanese Prime Minister Saad Al-Hariri.
Two members of Hamas were killed in an explosion in Beirut two weeks ago. According to Lebanon's state National News Agency, forensic experts determined that the blast was caused by a 15-kilogram charge of TNT placed underground in the city's Haret Hreik district. At a news conference last Sunday Hamas' top official in Lebanon, Osama Hamdan, cautioned the public not to jump to conclusions about the explosion, stressing that an investigation was "ongoing."
