BAGHDAD (AFP) - A spate of bombings targeting Shias across Iraq killed 22 people on Thursday, the latest in a spike in unrest amid weeks of anti-government protests and a political crisis engulfing the country. The attacks marked the third consecutive day of violence which has claimed 76 lives overall, including that of a Sunni Iraqi MP killed by a suicide bomber and 33 others who died in twin car bombs in an ethnically-mixed northern city. It comes as Iraq grapples with a long-running political dispute, with Prime Minister Nuri al-Maliki facing protests hardening opposition against his rule and calls from many of his erstwhile government partners for his ouster.
