US, Britain and France attack Syria. Russia responds: It will not sit idly by.
CCTV News:Regarding the precise military strike against Syria by the United States, Britain and France, Zhang Yuyao, a reporter from CCTV’s Asia-Europe Central Station, reported that just after the United States announced a military strike against Syria, Russian Duma officials responded that Russia expressed strong opposition to this military strike. This behavior not only violated international norms, but also was a naked violation of a sovereign country. Moreover, the behavior of the United States threatens Russia’s security, and Russia, as a nuclear power, will not sit idly by.

According to Russian media reports, the Russian Black Sea Fleet has sounded an air defense combat alarm on April 10, and the Russian armed forces stationed in Syria are currently in a state of readiness. However, the Russian military has not yet made any formal response to the military strikes by the United States, Britain and France. The United States also said that it did not inform Russia before the military action. The Russian Embassy in Syria said that it has not received any news of Russian citizens’ casualties in the military strikes.
