Suicide bomber kills four police in Chechnya
Four policemen were killed and four others injured on Sunday when they "foiled an attempt" by a suicide bomber to attack a concert hall in the capital of Chechnya, the Russian interior ministry told AFP.
The attacker blew himself up outside the hall where thousands were gathering for a concert to mark Grozny City Day in the regional capital, a ministry spokesman said.
He triggered the explosive after police securing the concert hall tried to inspect the man's identity papers, the spokesman added.
The concert also coincided with the birthday of strongman regional president, Ramzan Kadyrov.
Following a failed uprising against the Russian government in 1994-1996, the Chechen separatist movement became increasingly radical, evolving into a violent Islamist insurgency in the 2000s.
