The head of Russia's Federal Security Service (FSB) said on March 4 that there are suspects in the slaying of opposition politician Boris Nemtsov, but he gave no specifics and did not indicate authorities are close to solving the case.
Asked by journalists on March 4 whether there were any suspects in the case, FSB Director Aleksandr Bortnikov answered, "There always are."
Nemtsov, a vocal critic of President Vladimir Putin, was shot dead near the Kremlin late on February 27.
He was buried on the outskirts of Moscow on March 3 after an emotional ceremony attended by thousands of people.
Putin called the killing a "provocation" to destabilize the country and vowed to bring those responsible to justice.
Government opponents fear that may never happen, pointing to slayings of several Kremlin critics in the past that have gone unsolved.
Investigators said they were looking into several possible motives in Nemtsov's slaying, including Islamic extremism, the conflict in UKraine, and his personal life.
