Russia's lower parliament appears to be retaliating against a US law that targets Russian officials accused of corruption.

The Duma has already imposed restrictions on US pork and beef imports and is now considering a host of other punitive measures.

A trade bill passed in the US Senate on Friday will deny visas and freeze the assets of Russian officials linked to the death of a Russian whistleblower.

Sergei Magnitsky uncovered evidence of a $230m Russian tax fraud, but himself ended up accused of the crime.

He died in suspicious circumstances in a Moscow jail in 2009. Russian health officials deny the ban on US meat is politically motivated.
