MOSCOW, February 27. /TASS/. Russia’s Foreign Ministry is looking into reports that a father in the United States has killed two adopted children from Russia, the ministry’ human rights commissioner Konstantin Dolgov said on Saturday.

"Information that two adopted children from Russia might have been killed by a father arouses very serious concerns," Dolgov said. "We are actively verifying this information," he said.

The diplomat said Moscow’s possible further steps will be announced following the checks into the reports.

Russia’s lawmakers passed the so-called Dima Yakovlev law that took effect in January 2013 banning US citizens from adopting children in Russia. The legislation is named after a child from northwest Russia's Pskov region who died of heat stroke four months after being adopted by a US couple when his adoptive father left him in a parked car for nine hours.
