Thirty years after the deadliest homegrown attack in US history, former president Bill Clinton will return to Oklahoma City on Saturday to remember the people who were killed and comfort those affected by the bombing.

Mr Clinton was president on April 19, 1995, when a truck bomb exploded, destroying a nine-storey federal building in downtown Oklahoma City. He will deliver the keynote address at a remembrance ceremony near the Oklahoma City National Memorial Museum.
