Spain has the world's second-highest coronavirus death toll after Italy with 5,690 fatalities. The number of cases have jumped to 72,248 as the country moves to significantly increase testing.
The total is higher than the previous one-day death toll which was recorded on Friday of 769 people.
Madrid remains the worst-hit region, with 2,757 deaths and 21,520 infections, leaving hospitals and mortuaries overwhelmed, and the regional authorities working to open a second temporary morgue in an unused public building near the airport to house the dead.
An initial site was opened last week at the ice skating rink at the Palacio de Hielo (Ice Palace) shopping centre. With undertakers also overwhelmed, the government has authorised the army's involvement in the collection and transport of bodies for the duration of the state of emergency.
The latest figures came as Spain marked two weeks since the imposition of an unprecedented national lockdown which will remain in place until at least April 11.
Earlier on Saturday, Spain received a delivery of 1.2 million masks from China for health workers and those in the transport sector, the government said.
The delivery, which arrived at Madrid's Barajas airport, includes some 387,000 surgical masks for healthcare personnel, 75,000 masks for the security forces and more than 725,000 for those in the transport sector, from bus drivers to port and airport staff as well as those working for the postal service.
The current lockdown – one of the most severe in Europe – has been extended by the government until the 11th of April and is expected to be further extended.
Spain's foreign minister told The Guardian that the government was considering introducing stricter controls if these were deemed necessary.
Although Spain's latest figures showed a daily increase of more than 8,000 cases, the rate of new infections appears to be slowing, with officials saying the epidemic appeared to be nearing its peak.
