A mosque has been attacked in the Russian city of Volgograd, where a suspected female suicide bomber killed six people earlier this week.
Local police say an unknown attacker threw a Molotov cocktail at the mosque early on October 24.
Nobody was hurt in the incident.
On October 22, unknown individuals threw several Molotov cocktails into the house of a local Islamic cleric, which started a fire. Nobody was hurt in that attack either.
The attacks took place after an alleged female Islamist militant from Russia's North Caucasus republic of Daghestan blew herself up inside a bus in Volgograd on October 21, killing six men and women.
