The Irish Republican Army claimed responsibility for a bomb that exploded in a recycling bin in London on Saturday, the British Broadcasting Corp. reported Tuesday.
The BBC said a secretary at its Belfast radio offices received a call using a recognized IRA codeword."A device which exploded in London at the weekend was one of ours," the caller said.
No one was injured in the bombing, the third since the IRA ended a 17-month truce in its war against British rule of Northern Ireland on Feb. 9. A huge explosion that day in an east London business district killed two people and injured dozens.
Six days later, after telephone warnings, police defused a small bomb in a phone booth in the West End theater district.
On Feb. 18, a bomb exploded prematurely on a double-decker bus in the West End, killing the IRA man carrying it and injuring several others.
The IRA usually telephones warnings, but Saturday's explosion came without notice, police said.
