"sitting seconds earlier the bar s owner sean conlon said "
"the customer had just gotten up to go to the toilet so it s really "

"gasoline bombs inside the pub on the crumlin road an especially "
"polarized part of north belfast where catholic protestant tensions "
"have repeatedly flared "
"no group claimed responsibility for the attack on the thirty two "
"degrees north pub a catholic frequented bar across the street from a "
"hard line protestant district but catholic leaders blamed the largest "
"illegal protestant group the ulster defense association "
"firefighters quickly doused the flames caused by the gasoline "
"bombs the forklift remained wedged into the pub friday afternoon as "
"engineers and architects discussed whether the newly refurbished pub "
"would have to be partly demolished "
"the uda is supposed to be observing a cease fire in support of "
"northern ireland s 1998 peace accord but britain no longer recognizes "
"the validity of the uda truce because the anti catholic group has "
"violated it so often "
"the crumlin road area of north belfast has suffered some of northern "
"ireland s most graphic sectarian trouble in recent years while both "
"sides complain of suffering harassment and stone throwing protestants "

"force them from the area a charge the catholics deny. "
"protestant mobs in 2001 and 2002 blocked catholics from taking their "
