The announcement followed on the heels of Britain's order this week for 23 Russian diplomats to leave the United Kingdom because Russia was not cooperating in the case of Sergei Skripal and his daughter, both found March 4 poisoned by a nerve agent that British officials say was developed in Russia.
Johnson said Britain's National Security Council will meet this week to discuss "what further measures if any" the country will take.
Former double agent Sergei Skripal, 66, and his daughter Yulia, 33, remain in a critical condition in hospital, while Detective Sergeant Nick Bailey, who was exposed to the Novichok nerve agent while responding to the incident, is no longer considered critical. They believe the toxin was used in a dust-like powdered form and that it circulated through the vents of Skripal's BMW.
Britain and Russian Federation have each expelled 23 diplomats, broken off high-level contacts and taken other punitive steps in the escalating tit-for-tat dispute, which clouded the run-up to Sunday's presidential election in Russian Federation.

Western powers see the nerve-agent attack as the latest sign of alleged Russian meddling overseas. The tensions threaten to overshadow Putin's expected re-election Sunday for another six-year presidential term.
The foreign ministry said Moscow's measures were a response to what it called Britain's "provocative actions and unsubstantiated accusations".
Russian Federation goes to vote in the presidential election Sunday to elect Vladimir Putin for the fourth term in Kremlin. Russian Federation has demanded that Britain share samples collected by investigators. A strong showing would bolster Putin's assertion of a strong mandate to lead, and would likely further embolden him domestically and internationally.
Ukraine said the move was to protest voting Sunday in Crimea, whose annexation is still not internationally recognized.
