Prime Minister Benjamin Netanyahu will make a one-day visit to Sochi, Russia, to meet with Russian President Vladimir Putin on Thursday, five days before Israel's election.
The prime minister's office said that Netanyahu will take off in the morning and return in the evening.
During the brief half-hour meeting between the two leaders, Johnson and Netanyahu agreed on the need to prevent Iran from acquiring a nuclear weapon, Downing Street said.
Netanyahu also met with U.S. Secretary of Defense Mark Esper during his visit. U.S. Vice President Mike Pence was present in London at the time, though he did not meet with Netanyahu.
