English UK has joined other UK authorities urging students and families not to be alarmed, after London became the latest European city to be affected by terrorism.

Sarah Cooper, chief executive of English UK, said: "We are profoundly shocked by the act of one individual yesterday, and our thoughts are with the families of the visitors and Londoners who were caught up in this attack.

"But we have been encouraged by the quick and effective response of our police and security services. Londoners are back at work today, sad, but determined that our city will not be stopped by this one random attack.

"We would like to reassure students, their families, and agents that English UK member centres take their responsibility to protect students very seriously, and will be carefully monitoring the situation as it develops. Our accredited centres have the strictest regulations in the world on caring for under-18s and keeping them safe, and of course they will regularly update any advice given to adult students if necessary."

The Mayor of London, Sadiq Khan, has put extra armed and unarmed police officers on London's streets to keep visitors and residents safe after an attack which left two people, a police officer and the attacker dead. He said: "I want to reassure all Londoners, and all our visitors, not to be alarmed.

"Our city remains one of the safest in the world. London is the greatest city in the world and we stand together in the face of those who seek to harm us and destroy our way of life…. Londoners will never be cowed by terrorism."
