Earlier, the Interfax news agency reported, quoting an unnamed law enforcement source, that some shots were heard in the parliament, killing unspecified number of people.
Russian Interior Minister Rashid Nurgaliyev, who was currently in the regional capital of Grozny, has been informed about the incident, said the source.
Italian media is reporting that it was an assault on the Parliament by Chechen guerrilla militants, that is, Chechenyan Islamic terrorists. They report that there was a suicide terrorist who killed the two men from security who were at the Parliament’s entry door. Parliament’s president was inside the building when they stormed it, but according to sources he hasn’t been killed.
JPost reports that there are at least 4 killed. It also adds: “A separate group of attackers stormed the Ministry of Agriculture building, where they are fighting off police, Itar-Tass reported, citing a ministry source“.
UPDATE: The Telegraph reports: 6 people feared killed.
UPDATE – 2: Of the six people killed, 4 were attackers, according to latest reports.
Russia fought two wars with Chechen separatists in the 1990s before installing a loyal government there in 2000.
Since then, most of the Islamist insurgents have moved over into the neighboring Russian republics of Dagestan and Ingushetia, with terrorist attacks seldom striking at the heart of Grozny in recent years.
