A man who posted violent threats against President Joe Biden and other officials online was shot dead during an FBI raid on Wednesday.

Agents were attempting to serve an arrest warrant on Craig Robertson at his home in Utah, just hours ahead of a planned visit to the state by Mr Biden.

A criminal complaint said Robertson posted threats on Facebook against Mr Biden and a prosecutor pursuing criminal charges against Donald Trump.

The FBI declined to give more details.

The raid happened at about 06:15 local time in Provo, about 40 miles (43 miles (65 km) south of Salt Lake City.

A criminal complaint outlined messages that Robertson made on Facebook including pictures of guns and threats to kill Mr Biden and Alvin Bragg, the Manhattan district attorney leading an investigation into a hush-money payment by Mr Trump to an adult film star.
