US to impose sanctions on Russia over nerve agent attack

The United States will impose sanctions on Russia for its use of a nerve agent in an attempt to kill a former Russian spy and his daughter in Britain.
The State Department says Wednesday the sanctions will be imposed on Russia because it used a chemical weapon in violation of international law.
Former Russian spy Sergei Skripal and his daughter were poisoned by Novichok, a military-grade nerve agent, in the British town of Salisbury in March.
Britain has accused Russia of being behind the attack
