A bomb exploded in or beneath a car driven by Sergei Zavorotny, a Ukrainian journalist and politician described as pro-Russian, in Moscow's southern Chertanovo district. He was taken to hospital with serious injuries.

One report said the 72-year-old lost his left arm and suffered multiple fractures. Zavorotny had worked as an adviser and, briefly, spokesman for former Ukrainian prime minister Mykola Azarov, who fled to Russia in 2014. Ukraine had not responded to the attack.
