A prominent Russian writer and pro-war blogger has been wounded by a car bomb, officials say.
EDnews informs via BBC that Zakhar Prilepin, an vehement supporter of the Ukraine war, was reportedly conscious after the attack in the Nizhny Novgorod region but his driver was killed.
A suspect was detained, the interior ministry said.
It comes a month after another pro-Kremlin blogger, Vladlen Tatarsky, died in a bombing at a St Petersburg café.
Less that two hours after Saturday's attack was reported, the interior ministry said a suspect with previous convictions had been detained near a forest in the Nizhny Novgorod region.
"The search for possible accomplices continues," the statement said.
Nizhny Novgorod Governor Gleb Nikitin said: "Law enforcement officers are now investigating the circumstances and causes of the incident. Zakhar is OK."
The explosion reportedly took place on a remote road some 80km (50 miles) from the town of Bor. State media said the blogger suffered a concussion and fractured bones.
The partisan group Atesh, which is made up of Ukrainians and Crimean Tartars, claimed it was behind the attack.
"We had a feeling that sooner or later he would be blown up," they wrote on Telegram. "He was not driving alone, but with a surprise on the underside of the car."
The BBC cannot verify Atesh's claims.
As well as being one one of Russia's best-known novelists, Prilepin is known for his involvement with Russian ultranationalist politics.
A veteran of Russia's bloody wars in Chechnya in the 1990s, the 47-year-old has admitted fighting alongside pro-Russian separatists in eastern Ukraine.
