In Brazil, police raided the home of former president Jair Bolsonaro.

It is for a case of alleged falsification of Covid-19 vaccination certificates.

During the raid in the capital Brasilia, agents confiscated the former president's mobile phone.

In addition, six people were arrested as part of the same investigation, including a colonel allied with Bolsonaro.

Investigators seek to establish how the former president, a self-confessed skeptic of vaccination, appears in the records as "immunized" against the coronavirus.

One hypothesis is that, before leaving office last December, the far-right leader managed to falsify a certificate to travel to the US, which required vaccination to enter.

After the raid, Bolsonaro cleared himself of suspicion and said he had "nothing to hide".
