Russia's FSB security service said Saturday it had foiled an attack planned by a cell loyal to the Islamic State (IS) jihadist group in the country's unstable southern republic of Dagestan, arresting four people, Sputnik reports.
"Members of the group planned to detonate an explosive close to an administrative building belonging to security services, followed by an armed attack against interior ministry employees" in regional capital Makhachkala, the FSB said in a statement.
As well as arresting four "members of the international IS terrorist group", investigators found "firearms and bladed weapons, a large amount of ammunition and an explosive device", it added, along with mobile phones containing "exchanges with organisers located abroad".
