Russia's Domodedovo airport seems to be attracting a steady stream of trouble since last month.
At least 31 people were killed and 130 injured in a blast at the airport on Monday morning, according to the Associated Press.
While the cause of the blast is not yet determined, Moscow police have been put on alert for possible attacks in the city. Flights were redirected to other international airports in the region.
The airport has been often blamed for bad management, which resulted in the airport being shut down for nearly two days in December due to heavy snowfall.
Thousands of passengers were stranded at the airport during the peak holiday season.
Earlier this month, another jet exploded on the runway, leading to several flights been grounded. The chief inspector told NTV television that the blast might have been caused by violations of fire safety regulations or mistakes in the way the plane was used.
These disruptions have already resulted in the dismissal of the airport chief Vyacheslav Nekrasov.
However, these recent blast underline the seriousness of the conditions at the airport and necessitate further steps to improve management and security at Russia's most important international airport.
