PM expresses condolences to Russia over loss of lives in St. Petersburg metro

Prime Minister Narendra Modi on Thursday spoke to Russian President Vladimir Putin and expressed his deepest condolences to the government and the people of Russia on the tragic loss of lives in the blast in St. Petersburg metro.

?PM @narendramodi spoke to President Putin today. @KremlinRussia_E. PM expressed deepest condolences to the Government and people of Russia on the tragic loss of lives in the blast in St. Petersburg metro,? the Prime Minister?s Office (PMO) tweeted.

St. Petersburg was shaken by an explosion that tore through a metro train earlier on Monday, leaving at least 10 people dead and dozens injured.

The attack occurred as Putin was visiting the city to address a media forum and meet the Belarusian President Alexander Lukashenko.

"Naturally, we always consider all options -- both domestic and criminal, primarily incidents of a terrorist nature," Putin said.

The attacks come at a time of domestic political upheaval is Russia, as anti-corruption demonstrations have been held across Moscow and dozens of other cities over the past two weeks, with thousands of Russians taking to the streets to protest against corruption.
