Kyrgyz officials identified the suspect as Akbarzhon Jalilov, born in the city of Osh in 1995, and Russian officials confirmed his identity, saying he had also left a bomb found at another metro station before it went off.

But the Wednesday statement said, "At this moment, the investigators have no evidence of connection or acquaintance of the detained with executor of the terrorist action in the St. Petersburg metro (subway)".

Authorities in the mainly Muslim nation say Djalilov and his parents are ethnic Uzbeks with Russian citizenship and that Djalilov has lived in Russia since he was 16.

Reports in Russian Federation say one of the victims, Irina Medyantseva, died as she tried to shield her daughter from the explosion.

US President Donald Trump called Mr Putin to offer condolences over the attack.

The Investigative Committee said in a statement in the early hours on Wednesday that the investigators searched the man's home in St. Petersburg. The terror attack's death toll has risen to 14.

"I have already spoken to the head of our special services, they are working to ascertain the cause (of the blasts)", said Russian President Vladimir Putin, who was in St Petersburg at the time of the blasts, attending an economic forum.

The subway system in St. Petersburg, a city of 5 million that typically is crowded during peak commute hours, looked nearly deserted on Tuesday as many residents opted for buses.

The attack follows a long string of bombings of Russian planes, trains and transportation facilities.

Kyrgyzstan is a former Soviet republic which gained independence in 1991.

The Investigative Committee, the state body leading the investigation, said footage from security cameras near the same building showed Jalilov leaving, carrying a bag and a rucksack.

Officials said they were treating the blast as an act of terrorism, but there was no official confirmation of any link to Islamist radicals.

Police in the city are on high alert following Monday's explosion that killed the attacker and 13 other people and wounded 55 others.
