Kenya airport officials on Thursday arrested 21 travellers who were headed to Dubai, in the United Arab Emirates (UAE), using faked certificates declaring them free of Covid-19.
The arrests were made during an operation at the main airport in the capital, Nairobi.
Earlier this week the UAE decided to stop giving visas to citizens of 13 countries, including Kenya, Somalia, Libya, Tunisia and Algeria.
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 recorded 80,102 confirmed coronavirus cases including 1,427 deaths. On Thursday it tightened restrictions on public gatherings.
