The Russian authorities have detained a group of people who allegedly attempted to carry out terrorist attacks in the country, Russia's Federal Security Service (FSB) said Wednesday.

The suspects, who were from Central Asia, allegedly plotted to carry out a series of terrorist attacks during the May holiday celebrations in the Moscow region, the FSB said.

The suspects acted upon the orders of terrorist leaders in Syria and Turkey, it added.

There has been a growing concern over security in Russia after the country launched airstrikes against the Islamic State and other terrorist groups in Syria in September last year. Extremists have threatened attacks in retaliation for the air campaign.
