The death toll in Wednesday's terrorist attack near the U.K. Parliament has risen, after a 75-year-old man died of his injuries. Police say Leslie Rhodes of south London is the fourth person killed by British-born Khalid Masood, who was killed in the attack.

Other victims include Kurt Cochran of Utah, 54, whose wife was also seriously injured; Police Constable Keith Palmer, 48; and Aysha Frade, 43, who was reportedly on her way to pick her children up from school.
