The total number of COVID-19 cases in Yemen's government-controlled provinces increased to 222 on Sunday, as 10 new cases were confirmed.

The Yemeni Health Ministry said in a brief statement that "during the past 24 hours, 10 cases of COVID-19 were detected in four provinces controlled by the government."

The ministry said that the number of recoveries in the government-controlled areas increased to 10 since the outbreak of the novel coronavirus on April 10.

Also, the government announced that the death toll from the virus climbed to 42 in different areas under its control, including the southern port city of Aden.

The Yemeni government has taken several measures to contain the outbreak of COVID-19, including imposing a partial overnight curfew in Aden and other major cities under its control.

The government called on donors and relevant international humanitarian organizations to provide support to help contain the pandemic.

Yemen has been mired in a civil war since late 2014, when the Iran-backed Houthi group seized control of much of the country's north and forced the internationally-recognized government of President Abd-Rabbu Mansour Hadi out of Sanaa.
