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.
