Update: Boy, did I screw up trusting the media. As a twitter reader pointed out, Grozny is in Chechnya.
Meanwhile, there are unconfirmed reports Moscow has closed its airspace to all civilian traffic.
Reports on Twitter state there are fighter jets overhead as military helicopters cris-cross the city.
Russian media state President Vladmir Putin rushed to the Kremlin at 1.15am local time in response to reports of the outbreak of violence.
There’s reports Moscow airspace is closed, with fighters and helicopters overhead. This at the same time as fighting in Grozny would indicate that Russia at least suspects some militants are in Moscow.
H/T to Spill.
