Britain's Metropolitan Police say there are strong links between the Tunisian terror attack at the Bardo Museum in the capital, Tunis, and the slayings on the beach in Sousse.

Scotland Yard's Counter-terror commander Richard Walton did not offer details Wednesday.

British police traveled to Sousse after the June 26 attack that killed 38 tourists, 30 of them British, and have taken 459 statements from witnesses and people who were in the area that day. The Bardo attack killed 22.

Tunisian authorities have already drawn a connection between the attacks, saying that the Sousse attacker likely trained at the same Libyan jihadi camp as the two Bardo attackers. The assessment highlights the growing links between terrorists in the two countries, with Tunisians going to Libya to join the Islamic State group.
