World leaders have condemned the deadly Christmas Day bombings, carried out by Boko Haram yesterday, which claimed 39 lives and left 50 people injured, the BBC News reported.

According to reports, the United States White House has released a press statement condemning the attacks as “senseless violence” and while the UK described the attacks as “cowardly”.

The United States took it a step further, promising to assist the Nigerian government in bringing the criminals to justice.

“We have been in contact with Nigerian officials about what initially appear to be terrorist acts and pledge to assist them in bringing those responsible to justice,” the White House said in a statement.

Spokesman Jay Carney said: “We offer our sincere condolences to the Nigerian people and especially those who lost family and loved ones.”

French President Nicolas Sarkozy expressed “solidarity in [Nigeria’s] fight against terrorism”, while German Foreign Minister Guido Westerwelle said: “Even on Christmas Day, the world is not spared from cowardice and the fear of terrorism.”

UK Foreign Secretary William Hague said: “These are cowardly attacks on families gathered in peace and prayer to celebrate a day which symbolises harmony and goodwill towards others. I offer my condolences to the bereaved and injured.”

Israel promised to send medical aid and said it “condemned in the strongest terms these attacks carried out on Christmas Day”.

Boko Haram spokesman Abu Qaqa claimed responsibility for the blasts that ripped through Madalla in Niger State, Jos in Plateau State and Damaturu and Gadaka in Yobe State.
