6 arrested for terrorism in wake of St. Petersburg bombing
Russian authorities detained several people in St Petersburg on Thursday after finding an explosive device in one residential building and said they were investigating suspected accomplices of the man behind this week's deadly metro bombing.
He has been named as Akbarzhon Jalilov, a 22-year-old Kyrgyzstan-born Russian citizen who lived in St Petersburg for several years working as a vehicle repairman and later at a sushi bar.
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)". "President Trump offered the full support of the USA government in responding to the attack and bringing those responsible to justice", the statement said.
Both Mr Kaverin and another employee who found the unexploded bomb would be rewarded for their actions, metro officials said.
"And these procedures say that in this situation I had to take the train to the nearest station".
The investigators have searched Dzhalilov's home and found objects similar to those used in the subway bomb, it said.
The alleged attacker's distraught parents have flown to Saint Petersburg from their home city of Osh in southern Kyrgyzstan and were questioned by investigators.
In a meeting on Wednesday with the heads of security services from most of Russia's Central Asian neighbors, Russian President Vladimir Putin warned of the terrorist threat facing the region.
A blast inside a train on the St. Petersburg subway claimed 14 lives and injured dozens.
The impoverished, predominantly Muslim countries in Central Asia are seen as fertile ground for Islamic extremists, and thousands of their residents are believed to have joined the Islamic State group in Syria and Iraq.
Kyrgyzstan is a former Soviet republic which gained independence in 1991.
When Dzhalilov blew himself up, 10 other passengers were killed instantly.
Jalilov allegedly detonated an explosive on the city's metro between the central Sennaya Square and Tekhnologichesky Institut stations.
Officials said they were treating the blast as an act of terrorism, but there was no official confirmation of any link to Islamist radicals.
The bomb scare follows a train bombing on Monday that killed at least 14 people in Russia's second-largest city.
