A blast which ripped through a train as it travelled between two central subway stations in Russia's second‑largest city ‑ killing at least 11 people and injuring around 40 ‑ panicked the heart of one of the world's well‑known urban centres.
It also cut across the fault lines of a country grappling with its first signs of political upheaval in years.
Some have been calling for increased security measures to prevent further attacks; others warned of an impending crackdown.
Authorities launched a terrorism investigation that centred on a single bomber who left an explosive device at one central station before boarding a train and detonating a second device.
The city of St. Petersburg announced three days of mourning beginning tomorrow. The US Embassy in Moscow joined other countries in expressing condolences.
In Washington, President Donald Trump called the incident a "terrible thing."
