Saudi Arabia and other Gulf countries should understand that, if Syrian leader Bashar Al-Assad's regime collapses, the terrorist group Islamic State will come after them, Russian Security Council Deputy Secretary Yevgeny Lukyanov said.
"The states of this region, like Saudi Arabia, Gulf countries, and perhaps some others, should pray for Bashar al-Assad. This is the last security line for them," Lukyanov told journalists on Wednesday, according to Interfax News Agency .
"If Assad's regime collapses, Saudi Arabia and other Gulf countries will be the next targets for the IS," he said.
"There are some 5,000 of the Saudi king's subjects fighting for the IS. Where will they return when the active phase of the confrontation comes to an end there?" Lukyanov said.
