Head of al-Mustaqbal parliamentary bloc, former premier Fouad Saniora, on Sunday condemned “the criminal rocket attack that targeted neighborhoods in Beirut's southern suburbs,” describing it as a “dangerous development” and urging a “quick probe to identify the perpetrators and bring them to justice.”

"Those who committed this act are criminals who must be punished because sabotaging security and attacking innocent people is a service for Lebanon's enemies," Saniora said from Jordan, where he is taking part in the World Economic Forum on the Middle East and North Africa.

The rebel Free Syrian Army on Sunday condemned “in the strongest terms” the morning rocket attack on Beirut's southern suburbs, distancing itself from a threat by an FSA official that the “fire raging in Syria will spread into Lebanon.”

“We condemn in the strongest terms the act of sabotage and terrorism that targeted Dahiyeh and reiterate our commitment to Lebanon's security, sovereignty and stability,” Fahd al-Masri, head of FSA's Central Media Department, said in an interview with MTV.

Hassan is just 18 and a fighter with Hizbullah, which sent nearly 2,000 men to support the Syrian army's assault on the central town of Qusayr this week.

His father Ali was also among the ranks of the Hizbullah men battling rebels in the key town, many of them holed up in tunnels.

Caretaker Energy Minister Jebran Bassil slammed on Thursday the distribution of electoral districts in the hybrid draft law proposed by the March 14 coalition, calling it a “second Mountain War.”

"The proposal submitted by the Lebanese Forces and al-Mustaqbal blocs is a political Mountain War if we examine the divisions of the electoral districts they suggested,” Bassil stated in a press conference he held at his residence in al-Metn's Rabieh's neighborhood.

Syrian regime troops backed by Hizbullah fighters attacked the village of Hamadiyeh north of Qusayr of Wednesday, one of the last remaining rebel positions in the area, activists said.

"The Syrian regime is receiving help from Hizbullah and Iran. That's an increasing threat to regional stability," British Foreign Secretary William Hague told reporters at the Friends of Syria talks in Jordan's Amman.

U.S. Secretary of State John Kerry on Wednesday accused Hizbullah of dragging Lebanon into war, noting that thousands of the party's members are fighting in Syria.

In a joint press conference with Jordanian Foreign Minister Nasser Judeh in Amman, Kerry also voiced concern that chaos might spill over from Syria into Lebanon, condemning the intervention of Hizbullah and Iran in the Syrian crisis.

The March 14 General Secretariat condemned on Wednesday Hizbullah's fighting Syria, linking its involvement to the eruption of clashes in the northern city of Tripoli.

It said in a statement after its weekly meeting: “Hizbullah's unjustified war is part of its agenda to empty the Lebanese state of its institutions.”

The United States said Tuesday it does not differentiate between Hizbullah's armed and political wings as it again urged Europe to blacklist the group, a decision diplomats indicated could be imminent.

A formal request to brand the party as a terrorist group was filed by Britain and is to be discussed at closed-door talks June 4 of a committee overseeing the EU list of people and groups subject to its asset freezing regime, European diplomats said.

The rebel Free Syrian Army on Monday claimed that Hizbullah elusive commander Mustafa Badreddine -- who is accused of involvement in former premier Rafik Hariri's murder – is leading the group's operations in the Syrian town of Qusayr.

“It has been confirmed that Mustafa Badreddine is present on Qusayr's front where he is leading Hizbullah's operations,” said a statement issued by the FSA.

Israeli Defense Minister Moshe Yaalon stressed on Thursday that his country will not permit the transfer of weapons" from Syria to Hizbullah.”

Yaalon's statement came during talks he held with Director of the U.S. Central Intelligence Agency John Brennan, who arrived in Israel late on Thursday on a surprise visit to discuss the situation in Syria, an official Israeli source said.
