Paul Pelosi, the husband of US House of Representatives Speaker Nancy Pelosi, is recovering from surgery after being attacked by a hammer-wielding intruder at the couple's San Francisco home.

Mr Pelosi, 82, suffered a fractured skull and injuries to his right arm and hands but is expected to fully recover.

The attack has stoked fears about political violence in the run-up to the 8 November midterm elections. The suspect, David Depape, 42, is said to have demanded to see Mrs Pelosi.

President Biden described the attack as "despicable" and denounced a corrosive political climate for contributing to violence.

However, police investigating the attack on Mr Pelosi - which they have deemed an attempted murder - told reporters a motive had not yet been fully determined.

Mrs Pelosi - who was on the other side of the country in Washington DC at the time of the assault - flew back to see her husband in hospital.

Mr Pelosi had been attacked in the early hours of Friday morning "by an assailant who acted with force, and threatened his life while demanding to see the Speaker".
