Trump Calls Putin, Condemns St. Petersburg Metro Bomb Blast, Says It Was 'A Terrible Thing'

President Donald Trump called Russian President Vladimir Putin on Monday to offer condolences following the subway bomb blast in St. Petersburg. Twin explosions ripped through a metro car traveling between two train stations — Sennaya Ploschad and Tekhnologichesky Institute — Monday afternoon local time (around 8 a.m. EDT).

A White House statement confirmed the two leaders had spoken by phone.

"President Donald J. Trump spoke with President Vladimir Putin of the Russian Federation to condemn today's attack in St. Petersburg," the statement read.

Kremlin spokesman Dmitry Peskov also confirmed the phone call to Russian News Agency Tass, saying: "In a telephone conversation with Vladimir Putin, Donald Trump extended deep condolences to the families of those who were killed in a barbaric terror attack in St. Petersburg subway, and asked to pass on words of encouragement to the Russian people."

"Presidents consider terrorism to be an evil that should be tackled in a concerted effort," Peskov added, and specified that Putin and Trump "agreed to keep in touch."

While speaking to reporters on Monday prior to his working lunch with Egypt's President Abdel-Fattah el-Sissi, Trump called the Russian blast "absolutely a terrible thing" and added that "it's happening all over the world," according to the Associated Press.

The Kremlin honored the victims of the explosion, and offered support to families and friends of those killed or injured. Putin said the administration would carry out a full-fledged investigation into the incident.

"The causes of the explosion in the subway in St. Petersburg is not yet known, covers all versions - and domestic and terrorist act," Putin said of the investigation.

According to the latest data provided by a local news outlet Life, Monday's explosion killed 12 people and left 50 injured. The explosion took place while Putin was visiting St. Petersburg.
