• Charlie Kirk shooting – follow latest updates

• How the shooting unfolded – in maps, videos and images

US officials have issued an urgent appeal for help from the public as they continue to search for the shooter of conservative activist Charlie Kirk, releasing new videos and photos from the scene of the attack in Utah.

More than 24 hours after Kirk was shot while speaking in front of thousands of people at a Utah university, the state’s governor, appearing alongside FBI director Kash Patel and other officials, said “we need as much help as we can possibly get.”

Interior minister says ‘murder has been committed’ while US Congress demands justification for attack

None of the 11 people killed in a US military strike on a boat in the Caribbean last week were members of Venezuelan gang Tren de Aragua, Venezuela’s interior minister has said, while US media reported the attack came after the vessel had turned around and was heading back to shore.

The administration of Donald Trump has said the boat was transporting illegal narcotics, but has provided little further information about the incident, even amid demands from members of the US Congress for a justification for the action.
