Hundreds of people gathered in Northern Ireland on Sunday to commemorate the 50th anniversary of “Bloody Sunday,” one of the deadliest days in the Troubles.

On Jan. 30, 1972, British forces opened fire on civil rights protesters in Derry, also known as Londonderry, killing thirteen people and injuring 15 more.

Relatives of those slain and injured in the original march took part in a commemoration walk on Sunday, retracing their paths. Crowds gathered at the Bloody Sunday Monument for a wreath-laying service, which included Irish Premier Micheal Martin.
