Prime Minister David Cameron says there are strong indications it was an act of terrorism, and his top advisers will be examining the potential security implications of the attack, which took place near a London military barracks.

One of the attackers went on video to explain the crime — shouting political statements, gesturing with bloodied hands and waving a meat cleaver. Police shot and wounded the unidentified assailants and took them into custody.

Authorities did not identify the victim by name, but French President Francois Hollande referred to him as a "soldier" at a news conference in Paris with Cameron, who was visiting. Cameron would not confirm that, but British media say the victim was wearing a shirt in support of troops and Britain's Ministry of Defense said it was investigating whether a U.K. soldier was involved.

Security has been tightened at military barracks and authorities say they are updating their guidance for military personnel.
