Russian investigators search flat of suspected Saint Petersburg metro bomber's acquaintances

Russian authorities have defused an explosive device found in a residential building in St Petersburg just three days after a suspected bomber on the city's metro killed 14 people.

Thousands of people have gathered outside a St. Petersburg subway station to commemorate the victims of a suicide bomb blast that killed 13 train passengers and wounded about 50.

On April 3 at 14:40 in the third vehicle of train moving along the blue branch of the St. Petersburg subway a terrorist attack was committed.

Investigators gave no further details about Djalilov but his name and year of birth coincided with a statement from the Kyrgyz security services, which said earlier yesterday he was a naturalised Russian citizen originally from Kyrgyzstan.

Neighbours were moved away and witnesses said three men were led out in handcuffs, the agency said.

A source told The Daily Mail that "Two people are being sought on suspicion of planning the blasts, one of whom is thought to have placed the explosive device in the metro wagon and the second person for leaving a bomb at the metro station Ploshchad Revolutsii". The investigators suspect that they have been recruiting Central Asian men to join the ranks of the Islamic State of Iraq and Syria (ISIS) and other extremist organizations in St. Petersburg since November 2015.

Russian President Vladimir Putin has said between 5,000 and 7,000 people from Russia and other former Soviet republics were fighting alongside Daesh and other militants in Syria.

ISIS, however, has struck at Russian Federation overseas, claiming a bomb attack in October 2015 that blew a passenger jet packed with holidaymakers returning to Saint Petersburg out of the air over Egypt, killing all 224 people onboard.

The six detained were accused of recruiting "mostly immigrants from the republics of Central Asia to commit crimes of a terrorist nature and involvement in the activities of terrorist organizations banned in Russian Federation", including the so-called Islamic State, the statement said.

Russia's top investigative body said DNA evidence indicated that Jalilov also placed a bag containing a bomb at another subway station on April 3.

In the past two decades, Russian trains and planes have been frequent targets of attack, usually blamed on Islamic militants. The attack was carried out by a suicide bomber, but the bomber's intentions are still unclear. "The country and the entire world share our pain".

With St. Petersburg residents tense following the deadly subway bombing, the collapse of part of apartment building Thursday triggered fears of a new attack until city authorities explained the cause.
