Beirut- A US coalition warplane downed on Sunday evening a Syrian regime army jet as a response to attacks targeting a group of Kurdish fighters.

The coalition announced in a statement that a Syrian SU-22 jet dropped bombs near Syrian Democratic Forces positions in southern Tabqa.

“In accordance with its right to defend itself or its partnered force, the Syrian jet was immediately shot down by a US F/A-18 Super Hornet,” the statement said.

Meanwhile, the Syrian regime said in a statement that the pilot of the downed jet was missing.

The regime statement also claimed that its jet was downed while on a mission against ISIS militants.

On Sunday evening, rare fighting erupted between regime forces and SDF fighters in two towns located 40 kilometers south of the city of Raqqa, according to the Syrian Observatory for Human Rights.

Separately, Lebanese sources from the March 8 alliance said that “Hezbollah” is preparing for a battle to control the Syrian-Lebanese border by the end of this summer.

The “Hezbollah” battle, therefore, aims to secure the borderline stretching from the sea to the South and put it under the control of its fighters and those of the Syrian regime.

“Hezbollah is awaiting the results of some negotiations that would empty the area of Arsal’s outskirts, which the party is not allowed to enter on sectarian grounds,” the sources said.

“Even if the negotiations fail, the party has already made up its mind and is determined to resolve the situation on the border, the sources added.

Meanwhile, Iran’s Revolutionary Guards announced on Sunday that its paramilitary force launched surface-to-surface missiles into positions located in Syria’s Deir Ezzor.

In a statement, the Revolutionary Guards said the move came in response to the two recent attacks on Iran’s parliament and a shrine in Tehran, which were both adopted by ISIS.
