An explosion tore through a cafe Sunday in the Russian city of St. Petersburg, and preliminary reports suggested a prominent military blogger was killed and more than a dozen people were injured.

Russian news reports said blogger Vladlen Tatarsky was killed and 16 people were hurt in the explosion at the Street Food Bar No. 1 cafe in Russia's second-largest city. The reports did not mention any claim of responsibility or provide details beyond saying that a cafe visitor carried an "explosive device."
