Damascus: The Islamic State (IS) militant group downed a Syrian warplane in the Deir al-Zour province on Sunday, a media report said.
The warplane was engaged in striking IS positions in the al-Tharda mountain when it was shot down, the Syrian national TV said.
On Saturday, the US-led anti-terror coalition struck Syrian military positions in al-Tharda, killing 90 soldiers and injuring 110 others, which enabled the IS terrorists to take over the mountain but the Syrian army, under Russian air cover, succeeded in recapturing the positions later in the evening.
The Syrian government accused the US of supporting the IS and urged the international community to condemn the attack, Xinhua news agency reported.
The US strike marked its first attack on Syrian army positions since the coalition started its operations in 2014.
Meanwhile, the Syrian Observatory for Human Rights said the US-led airstrikes targeted government positions and added that the Russian counter-offensive against the IS militants in al-Tharda killed 38 IS militants.
