Ukrainian President Volodymyr Zelensky's wife, 42-year-old Olena Zelenska, has tested positive for Covid-19.

In a Facebook post, the president's office says the first lady is feeling well and has no symptoms. She is being treated in isolation from other family members.

President Zelensky, also 42, and the couple's two children have all tested negative.

Earlier this week, Zelensky revealed he had been fined for violating Ukraine's lockdown restrictions. This happened after he was pictured drinking coffee inside a cafe on 3 June - although a ban on catering services indoors was still in effect at the time.
