Russia arrests IS-linked suspects who plotted terror attack
None
Highlighting a new terror threat to Russia raised by its air campaign in Syria, security officials said Monday they have thwarted a planned attack on Moscow public transport system by militants trained by the Islamic State group.
Sunday's arrest of several terror suspects -- some of whom, intelligence officials say, were trained by IS in Syria -- has brought back memories of the string of deadly bombings that struck the Russian capital just a few years ago.
President Vladimir Putin has acknowledged the new danger, but insisted that launching the Russian airstrikes in support of Syrian President Bashar Assad's army was necessary to fight IS and other militant groups before they pose an even bigger security challenge to Russia.
