Authorities don't seem to know now whether this was a suicide bomb and the suspect is dead, or whether it was a bomb left at the station and the attacker got away. This is the photo released by Kyrgyzstan's GKNB security service of the suspect, 22 year old Akbarzhon Jalilov. But, Kyrgystan, while identifying the man in the photo, also says it has no idea if he committed the attack. It says its information comes from the Russians. This appears to be home-grown terrorism, not the work of an international group:

Rakhat Sulaymanov, spokesman for the country's secret service, said: "It was established, that the suspect in this act of terror was born in our republic. "It is probable that he acquired Russian nationality."

But there are other reports saying they are investigating whether the suspect had foreign ties to jihadist groups. Even more confusing, now there are other articles reporting that authorities say the suspect was not born in Kyrgystan, but somewhere else in Central Asia.
