Former FBI agent Peter Strzok, a favourite punching bag for Donald Trump and right-wing media, has said he still believes Russia and its president, Vladimir Putin, have kompromat on the president that prevents him from serving the “national interest” of the US.

“I believed at the time in 2016 and I continue to believe that Donald Trump is compromised by the Russians,” Mr Strzok said in an interview on NBC's “Meet the Press.”

“And when I say that I mean that they hold leverage over him that makes him incapable of placing the national interest, the national security ahead of his own,” said Mr Strzok, who led the FBI’s investigation into former Secretary of State Hillary Clinton’s use of a personal email server in violation of government security protocols.

At least 13 people died in a crush as partygoers tried to flee a Lima nightclub raided by police because it was in breach of coronavirus restrictions.

People were crushed to death or suffocated as around 120 people tried to escape the Thomas Restobar club on Saturday, national police and government officials said.

Local media reported that the victims were in their 20s.

A further six people were injured, including three police officers.

A statement from the Interior Ministry blamed the “criminal irresponsibility of an unscrupulous businessman” for the tragedy.
