At least 49 people have been killed and many others injured in three terrorist bomb attacks north and south of the Iraqi capital, Baghdad, security sources say.According to the Iraqi sources, two bombs exploded within minutes of each other outside a mosque in the city of Baqouba, north of Baghdad, on Friday as worshippers were leaving the weekly prayers. A total of 41 people were killed and 57 others injured in the explosions. Eight people were also killed after a roadside bomb exploded near a funeral procession in Madain, south of Baghdad. At least 25 others were also wounded in the attack. The attacks come a day after at least 22 people were killed and dozens injured in bombings in Baghdad and the northern city of Kirkuk. Insurgents affiliated with al-Qaeda have stepped up their attacks in Iraq over the past weeks targeting both Sunni and Shia Muslims. The United Nations Assistance Mission for Iraq (UNAMI) said on May 2 that April was the deadliest month in Iraq since 2008, as terrorist acts had killed over 700 people and injured more than 1,600 across the country. The UN mission also said Baghdad was the worst affected governorate with a total of 211 killed and nearly 500 injured.
