The total number of COVID-19 cases in Yemen's government-controlled provinces increased to 1,640 on Wednesday, as 11 new cases were confirmed.

Meanwhile, the number of recoveries in the government-controlled areas has increased to 751 during the past 24 hours since the outbreak of the novel coronavirus on April 10, the Yemeni health ministry said in a press statement.

The ministry also announced that the death toll from the respiratory disease climbed to 458 in different areas under the government control, including the southern port city of Aden.

The Yemeni 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 the capital Sanaa.
