The Iraqi government says six people have been detained in connection to the killing of a television journalist and her two-person crew.
The journalist, Atwar Bahjat of al-Arabiya, was gunned down with her cameraman and technician while reporting on last month's bombing of a Shi'ite shrine in Samarra.
The suspects were taken into custody in Samarra as part of a large-scale military operation that was launched Thursday.
The U.S. military says the operation, which involves U.S. and Iraqi forces, has resulted in the capture of 83 suspected insurgents and the seizure of 15 weapons caches.
In Baghdad Saturday, at least one Shi'ite pilgrim was killed in a roadside bombing. The U.S military also announced that two American soldiers were killed Thursday in Tikrit.
In a televised interview late Friday, President Bush's top security advisor, Stephen Hadley, said Iraq's military has made significant improvements and is taking more responsibility in securing the country.
