Meanwhile, the Lebanese National News Agency announced that eight Syrian refugees were injured in a drone explosion on the border with Syria.
The official Syrian news agency, SANA, quoted an unnamed Defense Ministry source as saying, "Lebanese Hezbollah militias fired several artillery shells from Lebanese territory toward Syrian Arab Army positions in the Qusayr area, west of Homs."
The source added: "Our forces immediately targeted the sources of the fire, after identifying the locations from which the five rockets had been fired."
He continued, "We are communicating with the Lebanese army to assess the incident. We have halted targeting the sources of fire inside Lebanese territory at the request of the Lebanese army, after it undertook to comb and pursue the terrorist groups responsible for targeting Syrian territory." The source did not specify the losses resulting from the shells.
While no official comment was immediately issued from Beirut, the Lebanese National News Agency reported Thursday evening that "eight displaced Syrians were injured and transferred by the Lebanese Red Cross to hospitals in Hermel (eastern Lebanon) as a result of a drone explosion on a farm in the town of Hawsh al-Sayyid Ali, on the border with Syria."
The agency indicated that the Lebanese army "quickly sent reinforcements to the area after hearing the sounds of gunfire."
While no party immediately claimed responsibility for launching the drone, Hezbollah did not comment on the Syrian statement.
Syria and Lebanon witnessed security tensions along their border in mid-March, following the Syrian Ministry of Defense's accusation that Hezbollah had kidnapped and killed three of its members.
At a meeting held in Saudi Arabia on March 28, Syrian Defense Minister Marhaf Abu Qasra and Lebanese Defense Minister Michel Menassa agreed on the strategic importance of demarcating the border between the two countries and coordinating their efforts to address security and military challenges.
During the meeting, Abu Qasra and Mansa signed an agreement affirming the strategic importance of demarcating the border between the two countries, forming legal and specialized committees in a number of areas, and activating coordination mechanisms to address security and military challenges, particularly those that may arise on their border.
The new Syrian government seeks to control the country's security situation and strengthen its grip on the borders with neighboring countries, including Lebanon, by pursuing drug smugglers and remnants of the former regime who are causing security disturbances.
The Lebanese-Syrian border is characterized by its geographical overlap, consisting of mountains, valleys, and plains with no signs or markings indicating the border between the two countries. The two countries are connected by six land border crossings along a length of approximately 375 kilometers.
