London attack victims: Veteran police officer, teacher killed

London (CNN)A veteran policeman and a teacher were among those killed in the terror attack that struck at the heart of the British capital Wednesday. Keith Palmer, a 48-year-old father and husband, had served as an officer for 15 years. He was on duty, unarmed, at the gates of Parliament when a man stabbed him to death. "He was someone who left for work today expecting to return home at the end of his shift, and he had every right to expect that would happen," Britain's most senior counter-terrorism police officer Mark Rowley said.
