Russian Foreign Minister Sergei Lavrov will self-isolate after coming into contact with someone who tested positive for Covid-19, his ministry said Tuesday.
Ministry spokeswoman Maria Zakharova wrote on Facebook that the minister, 70, "feels well" but that planned visits and meetings will be postponed to a later date.
On Monday, Lavrov was on a working visit to Athens where he was photographed wearing a mask during meetings with Greek officials.
According to Russian daily Kommersant, this was only the second time Lavrov was seen wearing a mask at a public event since the start of the outbreak.
Lavrov had been due to visit Bosnia and Herzegovina on Wednesday for talks with top officials and on Thursday he had planned a visit to Belgrade for a meeting with Serbian President Aleksandar Vucic.

Infections have been on a steady rise and reached record levels in recent days. On Tuesday the government tightened restrictions including with a requirement to wear face masks in many public spaces.
