Legal papers seen by the BBC show that 50 million masks ordered by the government to protect health workers from coronavirus will not be used by the NHS because of safety concerns.  The FFP2 respirator masks were bought by the Department for Health and Social Care as part of a £252m contract signed in April with Ayanda Capital Limited. But their use in the health service has been halted because they have loops which hook over the user's ears and there are concerns this may not provide a tight-enough fit to prevent virus particles from being inhaled. Ayanda Capital says its product meets the specification the government set out, but the British Safety Industry Federation told the BBC that masks which used ear loops were more likely to fail a face-fit test designed to ensure the wearer was protected. Other masks provided by Ayanda are not affected.

The contract was signed at a time when the government was under pressure to get on top of a shortage of personal protective equipment (PPE) for the NHS. 

The information about Ayanda's FFP2 masks was disclosed to the Good Law Project, which is trying to challenge the government over three PPE contracts it awarded, including Ayanda Capital's. The government told the BBC "there is a robust process in place to ensure orders are of high quality and meet strict safety standards, with the necessary due diligence undertaken on all government contracts".

Several officials from the port of Beirut have been placed under house arrest following Tuesday's explosion which killed at least 135 people and injured 4,000 more. The Lebanese government said house arrest would apply to any port official who "have handled the affairs of storing [the] ammonium nitrate, guarding it and handling its paperwork" since June 2014. Experts say the force of Tuesday's blast was about one-tenth of the explosive power of the atomic bomb dropped on the Japanese city of Hiroshima  during World War Two. More details have emerged about the cause of the explosion and how the ammonium nitrate ended up being stored there - here's what we know so far.

Countries around the world - including the UK - have offered humanitarian assistance to the Lebanese government after it said it lacked the equipment necessary to treat the injured and care for patients in critical condition.

Stories from Beirut people affected by the explosion continue to come in - including this one from Edmond whose wife Emmanuelle was giving birth when the blast happened.

Facebook and Twitter have taken action against the campaign to re-elect US President Donald Trump after it posted a clip from an interview with US TV network Fox News in which he claimed that children had immunity to coronavirus. His assertion runs counter to official US public health advice. Facebook said it had removed the video because it was in violation of its policies on coronavirus misinformation. Twitter said the Trump campaign account would be suspended until the tweet was deleted - which subsequently seems to have happened. Experts say children can catch and spread the virus but they're less likely to become seriously ill. Mr Trump has been pushing to get schools reopened across the US.
