国际英语新闻：Explosion at Moscow's airport kills at least 31

MOSCOW, Jan. 24 (Xinhua) -- At least 31 people were killed and over 130 were injured in an explosion at Moscow's Domodedovo airport on Monday, the Russian Health Ministry said.

The Russian Investigative Committee's Transport Investigative Department has confirmed that an explosion occurred at Domodedovo Airport's luggage reclaim zone at the international arrivals terminal.

But a spokesperson for the Federal Customs Services (FTS) told Interfax news agency that the blast happened in the lounge area near the Asia cafe next to an international departure area.

The preliminary reports suggest that it might be a suicide bombing, a source told local media.

Eyewitnesses said two terrorists blew themselves up when people emerged from the international arrivals zone.

"According to available information, an explosion occurred at Domodedovo's arrivals hall at 16:32 Moscow time (1332 GMT)," a spokeswoman for the investigation committee, Tatyana Morozova, said.

The Health Ministry said among the 130 injured, 20 are in serious condition.

A law enforcement source said three men are wanted in connection with the explosion.
