Suicide attacks against a military vehicle left four people dead and wounded three on Monday on the outskirts of Grozny, the capital of Chechnya, in Russia’s volatile North Caucasus region. A spokesman for the Russian Interior Ministry said two suicide bombers ambushed an armored military van near a police checkpoint outside of the city. The dual explosions killed three members of a military unit and wounded three others. A fourth body, presumed to be that of one of the bombers, was also found at the scene. The bombing is the first suicide attack in Grozny in nearly a year. Moscow has been battling separatists in Chechnya since the 1990s, but a leader backed by the Kremlin has cracked down on the insurgency.
