Syrian rebels received about 150 drones and other support from Ukrainian intelligence agents last month, weeks before their advance that led to the ouster of President Bashar al-Assad on Sunday, the Washington Post reports.

Citing unnamed sources with knowledge of Ukraine’s military activity, the newspaper reported that Ukrainian intelligence services sent about 20 drone operators and about 150 unmanned aerial vehicles four to five weeks ago to help the Hayat Tahrir al-Sham (HTS) group. ).

Russia’s foreign ministry had alleged, without providing evidence, that Syrian rebels received drones from Ukraine and were trained to operate them.

Kiev “categorically” rejected this claim.

HTS, a former al-Qaeda affiliate in Syria, formed a transitional government after Assad was ousted.

The Russian military has aided Assad’s forces, launching airstrikes against the rebels.

Russian bloggers also warned that Assad’s overthrow would endanger not only Russian military bases in Syria but also Russia’s very presence in the Middle East.
