Russian police arrest 3 suspected of links to subway bombing

Links between those arrested and the bomber are still being investigated, the agency said, but added that "clues" had been found at the suspected accomplices' addresses.

A bomb blast tore through a subway train under Russia's second-largest city Monday, killing several people and wounding more.

The Investigative Committee hasn't caught any associates of 22-year-old Akbarzhon Dzhalilov, a native of the Central Asian nation of Kyrgyzstan.

Officials of the Russian City of St. Petersburg said an explosive device found in an apartment building during a raid has been diffused by authorities.

Investigators suspect he was linked to radical Islamist groups and carried his improvised device in a backpack.

The blast came as Russian President Vladimir Putin was visiting the city, his hometown. Remains of the bomber are now being subjected to DNA testing, Interfax said.

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

"We see that, unfortunately, the situation is not improving", Putin said.

While searching the flat they had been living in, investigators said they had found "items of significance for the investigation".

Authorities in Russia and Kyrgyzstan identified the attacker as a Kyrgyz-Russian citizen, Akbarjon Djalilov.

A gathering in memory of the victims of the deadly St. Petersburg metro explosion will take place in the city on Thursday, St. Petersburg Governor Georgy Poltavchenko announced.

Late Monday, the White House said Trump called Putin to express his condolences for the bombing and to offer the full support of the United States "in responding to the attack and bringing those responsible to justice".

Islamic State - which has fighters from ex-Soviet Central Asia among its ranks - has repeatedly threatened to attack Russian Federation in revenge for Moscow's backing of Syrian leader Bashar al Assad.

Fourteen people were killed when the bomb went off inside a carriage on the St Petersburg metro system on Monday, dozens more were injured.

The killer's parents flew overnight to Russian Federation from their native Kyrgyzstan to help a probe that needs to clarify if he was working alone or is part of a terror group plotting other explosions.

Meanwhile, his parents - who have said they have not seen their son for quite some time - arrived in St. Petersburg on Wednesday for questioning.

"The conclusions of the genetic examination and the recording of the CCTV cameras give the investigators reasons to believe that it was Dzhalilov who committed the terrorist act in the train", said the RIC in a statement.

Vasilyeva reported from Moscow.
