Leading Arabic television channel Al Jazeera said Iraq's US-allied authorities had
extended a ban on the controversial broadcaster and closed its office in Baghdad.
Iraq's interim government first ordered the closure of Al Jazeera's Baghdad office for one month in August for backing "criminals and gangsters" by airing parts of videotapes from groups claiming to have seized or killed foreign hostages.
Al Jazeera officials said they were informed that the extension of the ban was indefinite.
"Al Jazeera channel is outraged at the decision taken...to extend the closure of its bureau in Baghdad," a statement said.
There was no word from the Iraqi government about the ban.
"We are also outraged at the procedures they have used. Police attacked our office this afternoon, took photographs and sealed it up," Al Jazeera spokesman Jihad Ballout told Reuters.
"Yes, we have been getting pictures out of Iraq, but like most others we are depending on the news and footage agencies to get our picutres. So we abided by the law."
Since the August 7th decision, Al Jazeera continued to carry scoops about kidnappings. Its main rival Al Arabiya has also carried such reports. Islamist groups have used Islamic Web sites to publicise the killing of hostages.
Al Jazeera, left with a largely free hand by its Qatari financers, has angered numerous Arab governments as well as Washington over its coverage of the war on Iraq, Afghanistan and Islamic militancy.
