Jordan’s Air Force is increasingly striking targets in Syria linked to drug and weapons trafficking.

According to the Syrian Observatory for Human Rights, a London-based war monitor, at least nine people were killed by the strikes in recent days.

“The situation has escalated to a concerning level to Amman officials, as smugglers recently began moving weapons and explosives across the border, increasing the security threat in Jordan exponentially,” a Syria expert at the International Crisis Group told DW.

So far, Syria has limited its reaction to condemning Jordan’s airstrikes. A recent statement from the Syrian Foreign and Expatriates Ministry said, “Such strikes at Syrian territories can’t be justified,” the state-run news agency Sana reported.

The statement, however, also emphasized that Syria aims to contain the situation “within its keenness not to cause tension between the two countries.”
