A police station was blown up by a suicide bomber in a town east of Algiers on Wednesday. Four officers were killed and almost 20 were injured.

This attack comes after the double suicide bombings which occurred on December 11. The two bombs hit the United Nations offices and a government building in Algiers killing 37 people.

Two people witnessed the bomb attack on Wednesday in Naciria and said that the car was racing towards the police station and exploded. The two witnesses were a journalist and a resident, according to the New York Times.

According to the Interior Ministry, four officers were killed and 20 people were injured, including eight officers. No other details were provided.

Al Arabiya satellite television said that Al Qaeda in the Islamic Maghreb is the one who carried the attack, but afterwards dropped the report.

On Thursday the responsibility for the attack was claimed by Al Qaeda in Islamic North Africa through a statement on their website.

The statement said: "With the grace and guidance of God, he surprised the apostates and destroyed the entire headquarters over their heads, leaving behind dozens of dead and injured among the police," FoxNews.com informs.

The statement also had a picture of the one who carried the attack.

It said that there are still "lines of martyrdom lovers" who are prepared to take part in new attacks and ask the security forces to "lay down their arms and remove themselves from the fight against the mujahideen."

Abdullah al-Shaayani is the one who carried the attack and the statement says that that the attack was a justification of the fact that the security forces “torture Muslim youth and shove them into dark prisons while waging war on jihad and the Mujahideen on behalf of their masters in the Elysee Palace and the White House.”
