BEIRUT, Aug. 23 (Xinhua) -- Lebanese officials and political figures condemned Friday recent deadly "terrorist" attack in the northern port city of Tripoli, which killed at least 29 people and leaving more than 500 injured.
Lebanese President Michel Suleiman in a statement called for " national solidarity to prevent the enemies of stability in Lebanon from reaching their goals," condemning the "massacre" in Tripoli as "another episode of a terrorist plan targeting the country."
He demanded the military, security and judicial bodies to " exert all efforts to expose the criminals and the inciters."
Suleiman cut short his vacation abroad to follow up the incident at home.
For his part, Speaker Nabih Berri said the attack in Tripoli was conducted by "the same terrorist and criminal hands" that killed dozens of people in Beirut's southern suburbs, referring to earlier bombing in the stronghold of military party Hezbollah.
Berri said in a statement that "Tripoli's twin blasts are the work of the same killers who orchestrated the Dahieh bombing, and we should face these killers on a united front."
A booby trapped car exploded on Aug. 15 in Dahieh of southern Beirut, killing 25 people and injuring more than 336 others.
Berri reiterated calls to "increase caution in the country and prevent its enemies from seeking any opportunity to attack it."
Caretaker Prime Minister Najib Miqati also condemned the twin bombings in his hometown, saying that they are a "clear attempt to create strife."
Miqati said in a statement "Tripoli and its residents, however, will once again demonstrate that they are more powerful than the conspiracy and they will not be lured toward strife."
He added "we urge them to exercise restraint and pledge that we will always be on their side."
On Friday morning, a blast rocked Tripoli's center near an old home of Miqati. A second bomb struck near the port of the restive city, close to the home of former Internal Security Chief General Ashraf Rifi.
Miqati has declared Saturday as a mourning day for the martyrs killed on Friday.
Hezbollah, for its part, condemned "the twin terrorist bombings that targeted innocent civilians in the city of Tripoli," urging " wisdom and awareness."
"These terrorist blasts are part of a criminal scheme aiming to sow strife among the Lebanese..., which serves the regional- international scheme seeking to fragment our region and drown it in seas of blood and fire," it added.
The party also urged "all wise people to preserve ... awareness and wisdom, and not to heed rumors and accusations seeking destruction for the country and its people."
