About 10,000 people shared in the funeral services. Bloody Sunday occurred when the IRA in Londonderry under the command of Martin McGuinness erected roadblocks that rendered Catholic districts of Northern Ireland’s second-largest city off-limits to police and troops. The Protestant government deployed Britain’s toughest military unit, the paratroopers, to confront an illegal march in January 1972. Soldiers stormed through the IRA barricades and shot 13 unarmed protesters. As Britain exonerated the troops’ actions, Catholic support for the IRA swelled. Britain abolished the Protestant government and took direct control of Northern Ireland as 1972 became the deadliest year of conflict, with more than 470 dead. (AP Photo, File)
