A police captain who worked at Moscow's Domodedovo airport has been arrested in connection with last month's bombings of two Russian airliners, the Interfax news agency reported Wednesday. The two planes blew up almost simultaneously on the night of Aug. 24, killing 90 people and marking the start of a series of horrific terrorist attacks blamed on Chechen rebels. A total of 430 people have died in the attacks. Citing an unnamed source close to the investigation, Interfax said that Capt. Mikhail Artamonov had been arrested and could be held for up to 30 days while authorities decide whether to press charges.
