A Covid-19 vaccination centre in Malaysia was ordered to close for sanitisation after more than 200 volunteers and workers there tested positive over the weekend, the country's science minister said.

Those inoculated from July 9-12 at the centre, about 25 km (15.5 miles) outside Kuala Lumpur, are advised to self-isolate for 10 days, Minister Khairy Jamaluddin told reporters.
