One police officer was killed on Sunday when a bomb exploded during a special operation in Russia's volatile southern republic of Chechnya, local police said.
Two soldiers were injured in the attack in the mountainous Urus-Martan district, around 20 kilometers south-west of the Chechen capital Grozny.
Russian federal troops fought two brutal wars against Islamist separatists in Chechnya in the 1990s and early 2000s. Security forces troops continue to fight militants in the region and its neighboring republics, where terrorist attacks are common.
