BEIRUT: The owner of the car that exploded in Beirut’s southern suburbs Monday night was questioned for twelve hours overnight, security sources said.

A home-made bomb including 700 grams of TNT grams bomb was planted in Abbas Mazloum’s car which exploded in the Hay al-Sellom area Monday night, sources said.

Another Syrian man, identified as Fahed al-Molla, is still giving testimony.

There are personal disputes between Mazloum and Molla and that the blast was likely due to conflict between them, the sources said.

Meanwhile, a judicial source told The Daily Star Tuesday that there are still no official suspects in the blast and that Mazloum and Molla are currently considered witnesses.

The source said that Military Judge Kamal Nassar, who is investigating the case, has also tasked the relevant security authorities to record the testimonies of shop owners in the neighborhood.

The explosion shattered windows in nearby shops in the neighborhood's crowded Abbas area, and left two people lightly wounded.

Hezbollah and allied Amal Movement gunmen, who maintain a heavy presence in the suburb, fired into the air after the blast.

Lebanese Army soldiers later deployed in the area and investigations into the incident began.
