In Iraq, attackers target security forces December 28, 2013 -- Updated 1320 GMT (2120 HKT) NEW: Violence flares in Mosul; security forces targeted Ahmed al-Alwani, a prominent Sunni politician, is arrested in a raid on his home He waged a campaign against the Shiite prime minister's government, calling it sectarian The government issued an arrest warrant for al-Alwani for allegedly inciting sectarian strife (CNN) -- At least 14 people were killed in Iraq on Saturday -- 12 security forces during attacks in and around Mosul, and two people during a raid on the home of a lawmaker in Ramadi. There has been an uptick of tension between the majority Shiites, who dominate government, and the disaffected Sunni minority. Mosul and Ramadi are predominantly Sunni cities where there is strong dislike of the central government. Police said four attacks occurred in the Mosul area, located in the country's north. It's where al Qaeda in Iraq -- a Sunni militant group -- has a strong presence. Six soldiers died in a suicide car bombing targeting a military post. Two police officers were killed in a suicide bombing and shooting at a police station. Two soldiers died in a roadside bombing. Gunmen shot dead two Kurdish security forces at an outdoor market. Lawmaker arrested in Ramadi In Ramadi, west of Baghdad, at least two people were killed when Iraqi security forces raided the home of Sunni lawmaker Ahmed al-Alwani and arrested him, police said. The Iraqi army clashed with al-Alwani's bodyguards, and al-Alwani's brother and a woman were killed during the raid. Eleven of al-Alwani's bodyguards were wounded. A few months ago, the central government issued an arrest warrant against al-Alwani for allegedly inciting sectarian strife. Al-Alwani is a prominent Sunni politician and one of the main organizers of the anti-government demonstrations in Anbar province that started about a year ago. Ramadi is the capital of Anbar province. He also waged a campaign against Shiite Prime Minister Nuri al-Maliki's government, accusing it of corruption and calling it a sectarian government.
