Russia's Lavrov: 'cynical' to call St Petersburg blast revenge for Syria

Russian Foreign Minister Sergei Lavrov said on Tuesday it would be "cynical and mean" to call a deadly blast in St Petersburg an act of revenge for Russia's actions in Syria, Russian state news agency RIA reported.

Russia authorities said the blast that killed at least 14 people in St Petersburg was carried out by a suspected suicide bomber with ties to what they called 'radical Islamists'.
