President Michel Suleiman stressed on Thursday that the same terrorists that carried out the blast in the Beirut neighborhood of Haret Hreik earlier in the day, are the ones planting terrorism, killing and destructing all Lebanese regions.

Suleiman's comments came shortly after a deadly explosion hit Beirut's Dahieh neighborhood, killing at least 4 people and wounding over 70 others.

The United States and the United Kingdom's embassies in Lebanon condemned on Thursday the “terrorist” bombing in Beirut's southern suburbs.

“We condemn today's terrorist bombing in (the Beirut neighborhood of) Dahieh,” the U.S. embassy said via its account on the social networking website Twitter.

An exchange of gunfire erupted on Thursday between the rival Tripoli neighborhoods of Bab al-Tabbaneh and Jabal Mohsen, in the wake of a deadly blast that rocked the Beirut southern suburb of Haret Hreik.

Heavy celebratory gunfire had erupted in Bab al-Tabbaneh as news broke that a bombing occurred in Hizbullah's stronghold in Dahieh, the thing that led to tensions in the two Tripoli districts.

Damascus "strongly" condemned on Thursday the deadly bombing that hit the southern Beirut neighborhood of Haret Hreik, calling for penalizing the “terrorists” behind it.

"Syria strongly condemns Dahieh's terrorist bombing,” the country's Information Minister Omran al-Zohbi told the state-run Syrian Arab News Agency.

The deadly explosion that hit Beirut's southern neighborhood of Haret Hreik on Thursday afternoon drew a wave of condemnation by local political leaders that considered that terrorism is targeting all Lebanese people.

The blast killed at least 4 people and wounded 75 others.

At least five people were killed and 77 others wounded in a car bomb attack that rocked the Beirut southern suburb of Haret Hreik on Thursday.

After state-run National News Agency said six people were killed and 75 others wounded in the blast, caretaker Health Minister Ali Hasan Khalil confirmed to several media outlets that the final casualty toll stood at 4 dead and 77 injured.

Iranian authorities demanded on Thursday to be informed about the probe with the “emir” of the Abdullah Azzam Brigades, Saudi national Majed al-Majed, who is supposedly detained by the army intelligence.

"The (caretaker) Foreign Ministry received a memo from Iranian authorities in which they asked to stay informed about the investigation with al-Majed, considering that the explosion took place on an Iranian soil,” caretaker Foreign Minister Adnan Mansour told LBCI television.

Marada Movement leader MP Suleiman Franjieh demanded on Thursday trying the reportedly held “emir” of the Abdullah Azzam Brigades, stressing that handing him over to another country is a “flagrant violation of Lebanese sovereignty.”

"A country that respects its sovereignty and its laws does not give both of them up in response to another nation's request, especially if the detainee is a dangerous person that wanted to incite strife,” Franjieh said in a released statement, soon after reports said several regional countries asked for handing Majed al-Majed over.

The army on Thursday arrested 11 people near the al-Beddawi Palestinian refugee camp in Tripoli on suspicion of their involvement in “recent bomb attacks.”

"As part of the mission of preserving security and stability, an army force arrested this afternoon 11 Syrians near the al-Beddawi camp in the North on charges of moving inside Lebanon without legal identification papers,” an army statement said.

The Lebanese Army's Airborne Regiment set up on Thursday new bases in eastern Lebanon's al-Qaa and Ras Baalbek regions, the state-run National News Agency reported.

The erection of the bases came after the Syrian army continued to attack areas lying on the northeastern border with Lebanon.
