BEIRUT, Jan. 2 (Xinhua) -- Lebanese leaders unanimously condemned the deadly explosion that hit Beirut's southern neighborhood of Haret Hreik Thursday, saying that terrorists are targeting the Lebanese people.
Lebanese President Michel Suleiman said that the terrorists that carried out the blast in Haret Hreik were planning to destruct all the Lebanese regions.
He stressed in a statement by his media office on "the importance of solidarity and of awareness of the dangers threatening Lebanon."
"Dialogue is also important between political leaders to protect the country against conspiracies aimed at shaking its stability," he added.
Lebanese Parliament Speaker Nabih Berri considered those behind Thursday's blast the same group that assassinated former Finance Minister Mohammed Shatah on Friday and planted bombs in the northern city of Tripoli.
Caretaker Prime Minister Najib Mikati said: "terrorists do not want stability for the country; they instead plan and execute a despicable plot that aims to promote sedition."
He called in a statement on all Lebanese factions to overcome their political splits and avoid "unilateral decision-making and exclusion."
Prime Minister-designate Tammam Salam also deplored the blast, calling for solidarity among the Lebanese people.
The blast came less than a week after a car bomb ripped through Beirut's central district on Friday, killing former Finance Minister Mohammed Shatah and seven others.
In Thursday's explosion, six people were killed at least and more than 70 injured.
The Lebanese army said in a statement that the car bomb detonated at about 4:10 p.m. local time (1210 GMT) in Haret al- Harayk's Areed Street.
The statement added that the explosion was caused by a 20-km bomb placed within a SUV.
"Investigations are underway to find out the method of detonation," the army said.
In November, two suicide bombings hit the Iranian embassy in southern Beirut 19, killing 25 people, and in the summer, the Beirut southern suburbs suffered two bomb attacks.
