Iran Press/ Europe: The state Investigative Committee said the writer's Audi Q7 was blown up in a village in the Nizny Novgorod region, about 400 km (250 miles) east of Moscow, which it was treating as an act of terrorism. It said Prilepin had been taken to hospital.
The committee released a photograph showing the white vehicle lying overturned on a track next to a wood, with a deep crater beside it and fragments of metal strewn nearby.
An interior ministry spokeswoman said a suspect had been arrested. State news agency TASS quoted security sources as saying they had found an apartment in the Moscow region where they believed the bomb could have been assembled.
Russian Foreign Ministry spokeswoman Maria Zakharova wrote on Telegram: "The fact has come true: Washington and NATO fed another international terrorist cell - the Kyiv regime."
She said it was the "direct responsibility of the U.S. and Britain", but provided no evidence to support the accusation.
Officials at the White House, Pentagon and State Department did not immediately respond to requests for comment. No comment was immediately available from Britain's Foreign Office.
