BAGHDAD (AP) -- Iraq's Shiite prime minister says an election law dispute likely to delay parliamentary elections is a threat to national security.

Nouri al-Maliki said in an interview with The Associated Press Thursday that a vice president's veto of the law could also hinder political reconciliation and economic development.

The constitution says the vote must be held in January, but election officials say they cannot meet that schedule because of the dispute.

Vice President Tariq al-Hashemi, a Sunni Arab, vetoed the law because he wanted more seats for Iraqis abroad, the majority of whom are Sunnis. He is now studying an amended version of the law that failed to satisfy many members of his once-dominant minority.

BAGHDAD (AP) -- Police and health officials say four people have been killed and at least 32 others wounded in two separate bombings south of Baghdad.

They said one of the Thursday attacks involved two home-made bombs that targeted a vegetables market in Mussayab, about 28 miles (45 kilometers) south of Baghdad, killing two people and injuring 26.

The second attack took place two hours earlier when a car bomb hit a suburban bus station in the Youssifiyah area just south of Baghdad. Two people were killed and six injured in that attack.

The attacks came on the eve of the Muslim Eid al-Adha holiday, which begins Friday for Iraq's Sunnis and Saturday for Shiites.

The officials spoke on condition of anonymity because they were not authorized to speak to the media.
