Monday, the Israeli military fired missiles into Damascus International Airport, killing four persons, including two Syrian troops, according to a human rights observer.

The attack, which occurred about 2:00 a.m. (2300 GMT), rendered the airport inoperable, according to SANA, Syria's official news agency.

Using "barrages of missiles," Israel targeted Damascus International Airport and its environs, a military source told SANA, which confirmed the deaths of two Syrian soldiers.

The Syrian Observatory for Human Rights, based in the United Kingdom and depends on a vast network of sources in Syria, reported that four individuals were killed in the early morning attack.

"Four fighters, including two Syrian soldiers, were killed" in the Israeli strike, the head of the Observatory, Rami Abdul Rahman, said AFP.

The missiles also struck "Hezbollah and pro-Iranian positions within the airport and its environs, including a weapons warehouse," according to Abdul Rahman.

Since the outbreak of civil conflict in Syria in 2011, Israel has conducted hundreds of air raids against its neighbor, hitting government troops and forces backed by Iran and Hezbollah fighters from Lebanon.

Israel seldom comments on allegations of its assaults, but it has stated repeatedly that it will not permit its archenemy Iran to establish a foothold in Syria.

The last time the airport was closed was in June, again due to Israeli air attacks.

The airstrike in Syria on Monday comes after the country's lowest annual death toll since the conflict began more than a decade ago.

According to data from the British-based Syrian Observatory for Human Rights, at least 3,825 persons were killed in Syria's civil conflict in 2022, a decrease from the previous year's tally of 3,882.

One thousand six hundred twenty-seven civilians, including 321 children, were murdered in Syria in 2022, according to the Observatory, which relies on a vast network of sources on the ground.

After years of deadly fighting and bombings in response to the violent suppression of anti-government demonstrations in 2011, the war has subsided mainly during the past three years.

Occasionally, warfare breaks out, and terrorist attacks persist, primarily in the country's east.
