A suicide bomber in the northeastern Iraqi city of Baqouba has killed twenty people attending a political rally, AP reported on Saturday.
A further fifty were injured after the bomber detonated his explosives at the same time as one of the candidates - Muthana al-Jourani - was hosting lunch for his supporters.
Attacks of this nature have swept across Iraq in recent months as sectarian tensions continue to rise. The Sunni minority are considered the most likely to carry out such bombings.
Iraq's Shia-led government has been accused of targeting its Sunni minority unfairly using new anti-terror legislation against them. The northern, predominently Kurdish, city of Kirkuk has also been the scene of violent attacks as the regional semi-autonomous government battles with Baghdad for control of oil contracts.
