Nine civilians, including two children, were killed on Thursday in suspected Jordanian airstrikes, likely targeting drug traffickers in Syria, as Jordan intensified border controls in response to increased smuggling attempts from Syria.

At least nine civilians, including two children, were killed Thursday in air strikes on Syria likely to have been carried out by Jordan against drug traffickers, a monitor and media outlet reported.

The kingdom has tightened controls along its frontier with Syria in recent years and its armed forces occasionally announce operations to foil drug and weapon smuggling attempts from its war-torn neighbor.

The Syrian Observatory for Human Rights monitors described the attack as a “massacre.”

The first strike on a house in the village of Urman killed a man, his wife, and their two daughters, along with his brother and his wife, said the Britain-based group.

The bodies of a man, his mother, and his aunt were found at the second house that was targeted, added the Observatory, which relies on a network of sources on the ground in Syria for its reports.

The Suwayda24 news website reported that air strikes “likely to have been carried out by the Jordanian air force” killed at least 10 people in Urman.

Observatory director Rami Abdel Rahman said Jordan’s armed forces often carry out deadly strikes on civilian homes “on the pretext of fighting drug trafficking.”

On this occasion, he said, it remained unclear if the two men targeted in the latest strikes were drug traffickers.

Rayan Maarouf of Suwayda24, an outlet run by citizen journalists, said however that the men who were killed, along with family members, were believed to have been drug traffickers.

One of the main drugs smuggled out of Syria is the amphetamine-like stimulant Captagon, for which there is a huge demand in the oil-rich Gulf.
