REPUBLIKA.CO.ID, JAKARTA -- The Indonesian government expressed its deepest condolences to the victims of a bomb blast on a St Petersburg train, Russia, and an attack in Syria's Idlib province.

"We extend our condolences to the families and friends of the victims of these attacks. These attacks are against humanity," Indonesia's Vice President Jusuf Kalla said here on Tuesday.

A bomb blast on a St Petersburg metro train killed 11 people and wounded dozens more.

The explosion occurred at around 2.30pm local time on Monday after the train had left Sennaya Ploshchad station in the centre of St Petersburg.

Meanwhile, an attack by Syrian government or Russian jets killed at least 35 people, including nine children, in the northwestern province of Idlib on Tuesday, a British-based war monitoring group stated.

Based on the United Nations' report released on March 3, 2017, at least 400 thousand people have died since 2011 during the Syrian conflict.

"We should not forget the Russian attack on the rebel-held area in Syria. The attack killed Syrian people. The assault is against humanity," the vice president remarked.

Furthermore, he called on countries involved in Syria's war to halt their operations and seek a peaceful solution that prioritizes humanity.

The suspected suicide bomber who killed 14 people on the St Petersburg metro system has been identified as a 22-year-old from Kyrgyzstan, the Russian security authorities has revealed.

The Indonesian government earlier extended its solidarity to the Russian government and its people over the incident.

There were no Indonesians among the victims.
