At least 60 extremists from this group, which was included in the international terrorism list, were transferred to the al-Shaddadi base where they are trained to attack the interests of the Syrian state, local activists informed SANA news agency.

These radical groups, according to SANA, were taken from the prisons controlled by the separatist Syrian Democratic Forces (FDS) militia, sponsored by Washington, and the transfer was carried out in helicopters and reconnaissance planes.

In April, the Pentagon airlifted a group of 50 extremists to the al-Omar oil field where Washington established a base there.

The mission of these mercenaries is focused on destabilizing the Government-controlled areas by attacking points of the Syrian army and civilian communities, in addition to protecting the oil facilities occupied by US troops, SANA news agency informed.
