Speaker Nabih Berri has said that the closure of the notorious block B of Roumieh prison east of Beirut was the result of the dialogue between Hizbullah and al-Mustaqbal that started last month.

“The operation at Roumieh prison came as a repercussion to the dialogue ... which proved that the state exists,” Berri told his visitors.

The army on Tuesday arrested a Lebanese man in the northern city of Tripoli on suspicion that he was plotting to carry out a suicide bombing, while two other people were captured in Bekaa's Arsal after trying to cross into its outskirts.

The army said in an official statement that its forces arrested “in Tripoli's al-Mankoubeen area the citizen Bassam Hussam Naboush on suspicion that he is a would-be suicide bomber.”

Progressive Socialist Party chief MP Walid Jumblat lauded on Tuesday security forces and Interior Minister Nouhad al-Mashnouq on the successful operation that led to the closure of the notorious block B in Roumieh prison.

“I salute the Internal Security Forces that executed with an admirable success the operation at Roumieh prison and imposed the authority of the state,” said Jumblat via twitter.

Suicide bombers affiliated to fugitive Ousama Mansour have been detected in several areas in the northern city of Tripoli as media reports said that his wanted accomplice Shadi al-Mawlawi is directly linked to the two men who carried out the Jabal Mohsen attack.

An Nahar newspaper reported on Tuesday that the movement of around ten members of Mansour's group have been perceived in the north. They are reportedly carrying explosive belts.

Justice Minister Ashraf Rifi has revealed that he asked the judicial authorities to refer the latest attack in the northern city of Tripoli to the Judicial Council as reports emerged that the suicide bombers received orders from top wanted terrorists Osama Mansour and Shadi al-Mawlawi.

Rifi told local dailies published on Monday that he gave orders for the attack on a cafe in Tripoli's mainly Alawite Jabal Mohsen neighborhood to be referred to the Council similar to the bombings of the Sunni al-Salam and al-Taqwa mosques in 2013.

Prime Minister Tammam Salam stressed on Monday that the country's front is holding up amid the ongoing dialogue between the political arch-foes, considering the measures against Syrians along the border as merely “humanitarian.”

“Terrorism has no limits but security forces were able to thwart a large number of terror attacks that don't only aim at killing people but planting division,” Salam said in an interview with Ad Diyar newspaper.

Speaker Nabih Berri praised the residents of Jabal Mohsen in the northern city of Tripoli after the suicide attack that targeted a packed cafe on Saturday and stressed that talks between Hizbullah and al-Mustaqbal began showing their fruits.

Local dailies published on Monday quoted Berri as telling his visitors that “we won nine martyrs and the terrorists lost two” men.

The United Nations Security Council has “strongly condemned” the suicide bombing in the northern city of Tripoli and expressed its determination to combat terrorism on all fronts.

In a press statement issued on Sunday, Council members reaffirmed that “terrorism in all its forms and manifestations constitutes one of the most serious threats to international peace and security, and that any acts of terrorism are criminal and unjustifiable regardless of their motivation.”

Grief engulfed the Tripoli district of Jabal Mohsen on Sunday during the funeral of nine victims who were killed in yesterday’s twin suicide bombing, as the city's leaders stressed the need to “pursue the criminals” and stand by the state and its security forces.

Head of the Islamic Alawite Council Sheikh Assad Assi led a huge crowd of mourners, only hours after the evening attack on a popular Jabal Mohsen cafe that also left 37 people wounded.

The United States on Sunday condemned the Jabal Mohsen suicide bombing that killed nine people and pledged its support for Lebanon's security forces.

"The United States strongly condemns yesterday’s suicide bombing at the Omran Cafe in the Jabal Mohsen neighborhood of Tripoli, Lebanon," said Marie Harf, the State Department's deputy spokeswoman.
