A blast has ripped through the baggage reclaim area of Moscow's Domodedovo airport, killing at least 35 people and leaving more than 100 people injured.
The device, thought to be the work of a suicide bomber, exploded at around 1.30pm local time on January 24, reports say.
Despite the blast, the situation at Moscow's largest airport seemed to quickly return to normal.
According to the official website, flights appear to be departing and arriving at Domodedovo, and British Airways has not cancelled its flights to the airport.
Media reports are focusing on whether the bomb was down to Islamist insurgents from the volatile Caucasus region.
In March last year 40 people were killed and more than 80 injured after two female suicide bombers attacked Moscow's Metro during the busy rush hour.
