An unspecified number of people have sustained injuries after Israeli warplanes carried out a string of airstrikes against several border crossings between Syria and Lebanon, in the latest act of aggression against the Arab country since the collapse of the government of Bashar al-Assad.

The so-called Syrian Observatory for Human Rights said on Friday that the overnight strikes put an “unofficial crossing” near Lebanon’s frontier town of Wadi Khaled, which borders Syria’s province of Homs, “out of service” and wounded several people.

The Britain-based war monitor added that the aerial attacks came “after a convoy of vehicles was observed headed from Syria towards Lebanon.”

The Observatory chief Rami Abdel Rahman reported “heavy material damage to buildings and vehicles”.

Lebanon’s official National News Agency reported “enemy aircraft flying at low altitude over the city of Hermel” and villages in the Bekaa Valley in the country’s northeast near the Syrian border.

The Israeli military alleged in a statement that its air forces “struck crossing points in the area of the Lebanon-Syria border,” claiming that they were used by Hezbollah resistance movement to bring reinforcements into Lebanese territory.

Following the downfall of Assad’s government in early December last year, the Israeli military has been launching airstrikes against military installations, facilities, and arsenals belonging to Syria’s now-defunct army.

The occupying regime’s attacks have drawn widespread condemnation for violating Syria’s sovereignty and devastating assets belonging to the Arab nation.

In the wake of the fall of Assad, Israel, which has occupied the Syrian Golan Heights since 1967, also invaded a UN-patrolled buffer zone in southwestern Syria, taking over the Syrian side of Mount Hermon, known as Jabal al-Shaykh in Arabic, as well as several Syrian towns and villages.

Israel has also come under scrutiny over the termination of the 1974 ceasefire agreement with Syria, and exploiting the chaos in the Arab nation following Assad’s downfall to make a land grab.

The United Nations created the buffer zone in the Israeli-occupied Golan Heights after the 1973 Arab-Israeli War. A UN force of about 1,100 troops had patrolled the area since then.
