The Army of Ansar al-Sunna, one of Iraq's most active terrorist groups, has claimed the assassination of a senior judge, as it intensifies its campaign to intimidate Iraqi voters just days before national elections.

In an Internet statement that has not been authenticated, the group says it killed the administrator of Iraq's judges and vowed to do the same to what it called other infidels and apostates.

The judge, Qais Hashim Shameri, died in a hail of bullets Tuesday as he drove through Baghdad. Another person in the car was also killed.

Meanwhile, the U.S. military says five soldiers were killed in a vehicle accident north of the Iraqi capital Monday evening. A sixth soldier died Monday after being seriously wounded in a roadside blast in Baghdad.
