The Pentagon is yet to officially acknowledge the downing of a surveillance drone over ISIS-free territory controlled by the Syrian govt, but scarce details of the incident hint at US involvement going beyond its self-mandated anti-ISIS plan in Syria.

Anonymously, US military sources have confirmed that the country has lost contact with one of its drones over Syria, after SANA news agency reported Syrian government forces shot down a hostile drone in Latakia province. Sources however did not reveal the cause of the incident.
