According to World Health Organization figures, Spain has seen over 7,700 cases of coronavirus and 288 deaths as of March 15.

 The spike prompted Prime Minister Pedro Sanchez' government to declare a state of emergency on Friday.

All its 40 million-strong citizens have been asked to stay indoors apart from necessary trips - a policy that had already been implemented by virus-ravaged Italy.

Worldwide, the death toll from COVID-19 has now passed 6,500 with over 169,000 confirmed cases of the disease, despite a significant reduction in the number of new cases in China.

Spain's tactics bear some resemblance to reported surveillance tactics used by China, which deployed drones, robots and facial recognition software in an attempt to curtail the outbreak. China's English-language newspaper the Global Times shared footage in January showing a drone telling off citizens for going out without masks or to stay indoors.
