MOSCOW (Reuters) – An explosion near a Moscow market popular with foreign tourists injured a woman on Thursday, police said.

Police did not say whether the blast was a bomb or not, although the RIA Novosti news agency later quoted a security source saying it had been a 50-gram bomb.

“I confirm there has been an explosion,” a spokesman for the police at the Moscow city administration said. “But I don’t have any information on whether it was a bomb.”

The explosion occurred outside a cafe near the Ismailovsky market in the east of the city, he said.
