British Foreign Minister Boris Johnson canceled a visit to Russia, scheduled for April 10. He wrote about this on his Twitter page.
"I will now not travel to Moscow on Monday 10 April. My priority is talks with my G7 counterparts about Syria and Russia's support for Assad," he wrote.
In a statement published on the website of the British Foreign Ministry, Johnson stressed that he had discussed the current situation with US Secretary of State Rex Tillerson.
"He, as planned, will visit Moscow and after the G7 summit will be able to convey this clear and coordinated message to the Russian side," said the head of the British Foreign Ministry.
Johnson noted that London regrets that Russia continues to defend the Assad regime even after an attack using chemical weapons against innocent civilians.
"We urge Russia to do everything possible to achieve a political solution in Syria and work with the rest of the world community to ensure that the shocking events of last week never happen again," the statement said.
