Technology companies must cooperate more with law enforcement agencies and should stop offering a "secret place for terrorists to communicate" using encrypted messages, British Interior Minister Amber Rudd said on Sunday.
Rudd also appealed for cooperation from the owners of encrypted messaging apps such as Facebook's WhatsApp, backing away from seeking to introduce new legislation.Rudd added: "There should be no place for terrorists to hide. We need to make sure organisations like WhatsApp, and there are plenty of others like that, don't provide a secret place for terrorists to communicate with each other." "We need to make sure that our intelligence services have the ability to get into situations like encrypted WhatsApp," she said. 
Local media have reported that British-born attacker sent an encrypted message moments before killing four people last week near the British Parliament on Wednesday after ramming a car into pedestrians on Westminster Bridge in London.
