British authorities said Wednesday detectives have officially linked Tunisia's beach massacre and a terror attack at a museum in the nation's capital — but would not explain how.

Thirty-eight foreign tourists — mostly British citizens — died when a gunman opened fire on the beach in Tunisia's resort town of Sousse in June. The attack deeply rattled Tunisia, which was still reeling from March's deadly assault on the Bardo Museum in Tunis.

British counterterrorism officers have been working with Tunisian authorities to investigate the attacks and on Wednesday said the two were "officially" connected.

Commander Richard Walton, head of the counterterrorism command at London's Metropolitan Police, said in a statement that the Bardo attack "is now being linked to the Sousse murders."

"I cannot go into further details regarding this live investigation," he added, saying that British officers were working closely with Tunisian authorities and had informed them of the connection.

ISIS claimed responsibility for the attack on Sousse. One of the suspected gunmen in the Bardo Museum attack was believed to have links to al Qaeda's north African arm.

ISIS and al Qaeda are at odds with each other, though movement between the two groups by militants is not unheard of.
