The US military has moved a new truck-mounted, long-range rocket launcher from Jordan to a US base in al-Tanf in Southeastern Homs, near the Iraqi and Jordanian borders, stepping up its presence in the area, two regional intelligence sources said.

Axar.az reports citing IRNA.

They said the (High Mobility Artillery Rocket Systems - HIMARS) had moved into the desert garrison, which has seen a buildup in recent weeks as tensions escalate after the US-led coalition struck positions of the Syrian forces to prevent them advancing toward the al-Tanf base, Reuters reported.

"They have arrived now in al-Tanf and they are a significant boost to the US military presence there," one senior intelligence source said, without elaborating.

The HIMARS had already been deployed in Northern Syria with US-backed forces battling ISIL militants, he added.

The missile system’s deployment at al-Tanf will give US forces the ability to strike targets within its 300-kilometer range.

Washington deployed the HIMARS on the Turkish border to strike at ISIL outposts. They were used several times from the Jordanian border to hit militants who had a foothold in the Southeastern desert.
