Kenya airport officials on Thursday arrested 21 travellers who were heading to Dubai, in the United Arab Emirates (UAE), using fake Covid-19-free certificates.
The arrests were made during an operation at the main airport in the capital, Nairobi.
It came hours after the UAE banned the issuance of visas to travellers from several countries including Kenya.
Local media report that the ban was imposed after travellers from Kenya were found with fake certificates upon arrival in the Gulf state.
Kenya has been recording increased Covid-19 cases, with the total number of confirmed cases now at 80,102 including 1,427 deaths.
