The US secretary of state, Marco Rubio, has said the US is closely monitoring the case of a Russian laboratory worker who died last week after a reported accident at a plague research institute in Siberia.

“We’re watching and monitoring it closely,” Rubio said on Monday before leaving for a trip to Europe. “I ⁠don’t think it’s cause for alarm, but it is cause for focus and a cause just to keep an ⁠eye on it.”
