An additional shipment of 8,000 tests is expected to arrive in the Yemeni city of Aden in the coming days.

"These test kits will allow wider testing for Covid-19 across the country and the timely management of confirmed cases to save lives," said Sara Beysolow Nyanti, Unicef's representative in Yemen.

Last month the United Nations warned that the health system had effectively collapsed in Yemen, which officially confirmed its first Covid-19 case on 10 April.
