Islamists claim small Moscow blast
An Islamic group founded by a Chechen warlord claimed responsibility Friday for a small blast that went off at a bus stop near the training centre for Russia's FSB security service in Moscow.
No one was hurt in Wednesday's explosion and police investigating the case said they suspected it was linked to "hooliganism".
But a statement from the Riyadus Salikhin Martyrs Brigade posted on the Kavkazcenter.com website popular with Islamists claimed the explosion, saying it was carried out in reprisal for past FSB operations in the Caucasus.
"We intend to continue striking facilities and places where the (FSB) criminals gather," the statement said.
The Riyadus Salikhin Martyrs Brigade was established in 2001 by the Chechen warlord Shamil Basayev, who died in a blast that was later claimed by Russian security services in July 2006.
Wednesday's explosion came after a blast in January killed 37 people and wounded more than 100 in Moscow's busiest airport Domodedovo.
After a lull of several years, suicide attacks returned to Russia last March when two female suicide bombers from the Caucasus killed 40 and wounded dozens on the Moscow underground.
One of those two underground blasts occurred near the FSB headquarters in central Moscow.
Russia's leading Islamist rebel Doku Umarov has claimed both attacks and vowed to make 2011 "a year of blood and tears."
