Whether in the Middle East or Iraq or Africa terrorism can strike anywhere, anytime, even Muslim killing Muslim while they pray in a Mosque.

Algeria: Al-Qaeda raids mosque, kills two, saying “We kill you with Allah’s consent”
I don’t know what a “moderate Salafite” would be. A Salafi is one who adheres to “pure Islam,” and hence holds to the same goals regarding political Islam that Al-Qaeda itself champions. Perhaps they differ on the means to attain those goals.

“Algeria: Al-Qaeda attacks moderates,” from AKI (thanks to Sr. Soph):


Algiers, 18 March (AKI) – Members of the al-Qaeda in the Islamic Maghreb militant group in Algeria have reportedly attacked members of a moderate organisation opposed to its terrorist activities.
A report on Tuesday in the Algerian newspaper el-Khabar said an al-Qaeda militant carried out a raid against a mosque in the Algerian province of al-Wadi on Sunday night and killed two men while they prayed.

According to the report, eyewitnesses said masked men entered the mosque as evening prayers were being held forcing everyone to fall to the ground.

The armed militants called for the two men, Harun Ahmad, and his cousin, Harun Abdel Jabbar, to step forward. They were then taken to the courtyard in the mosque where they were shot to death as the killers, speaking in an Algerian dialect, said: “We kill you with God’s consent.”

The two victims were part of a group of moderate Salafites who are opposed to the terrorist activities carried out by the al-Qaeda in the Islamic Maghreb group.

According to investigators, the two men were murdered by a local leader of of the Islamic terrorist group, Masoudi Muhammad al-Hafith.

Another moderate Salafite was killed in the same area in a similar situation in March 2006.

Salafites are Muslims who adhere to a pure interpretation of the Koran and are inspired by the lives of the first Muslims.
