LONDON - Britain suffered its third major extremist attack in three months on Saturday night when three men using a van and knives killed seven people in a busy area of London. This is how the attack at London Bridge and nearby Borough Market, which also left dozens injured, unfolded:
9:58 p.m., Saturday, June 3: A van entered London Bridge crossing the River Thames from north to south. The van mounted the sidewalk on the bridge and struck pedestrians. It later crashed outside the Barrowboy & Banker pub near stairs leading down to Borough Market. Three men left the vehicle and headed into the market, where they began stabbing people in pubs and restaurants while patrons and workers took cover and tried to help the wounded.

10:16 p.m.: Eight minutes after police were first called, three male suspects were shot dead by eight armed officers near the Wheatsheaf pub on Stoney Street. A member of the public is also wounded in the "unprecedented" police gunfire, but not critically injured.
12:25 a.m., Sunday, June 4: Police declare the attacks on the bridge and at the restaurants and pubs as terror attacks.
