Security officials speaking on condition of anonymity on Saturday said explosions targeted the Omran café in the majority Alawite neighborhood of Jabal Mohsen.

The security source told AFP: "The first suicide bomber entered into the Ashqar cafe at around 7:30 pm (1730 GMT) and blew himself up."

"Then, a second suicide attacker arrived, and blew himself up too," he said, updating his initial account of a single suicide bomber.

Security officials cordoned off the coffee shop after the blasts.

According to sources from the Arab Democratic Party, the dominant party in Jabal Mohsen, two bombers were behind the attacks. One of them entered the café, but the second one couldn't and blew his bomb outside.

The terrorist Nusra Front claimed via Twitter responsibility for the terrorist attack as the National News Agency (NNA) mentioned that the two suicide bombers who carried out the Jabal Mohsen blasts are Taha Samir Khayal and Bilal Mohammed Mare'yan, known as Ibrahim, from the area of Mankoubeen adjacent to Jabal Mohsen.

Over the past months, Lebanon’s second largest city, Tripoli, has been rocked by turmoil due to the conflict between supporters and opponents of the government of Syria’s President Bashar al-Assad.
