BAGHDAD (AP) -- Gunmen suspected of being Shiite militiamen burst into the offices of four independent newspapers in Baghdad, smashing their equipment, stabbing and beating employees, and even hurling one reporter from a roof in the most brazen attack against journalists in Iraq this year, said staff and officials on Tuesday.
Two editors said they believed their assailants were members of a Shiite militia, saying the raids came after their newspapers published stories criticizing their hardline cleric-leader. It underscored the dangers facing the media in Iraq, one of the most dangerous places in the world for reporters.
"The message of the assailants was to shut mouths," said Bassam al-Sheikh, editor of one of the attacked newspapers, Al-Dustour. "This is a dangerous precedent."
A government spokesman condemned the attacks.
Some 50 assailants participated in Monday's attacks, according to a notice left on one of the newspaper's websites and according to al-Sheikh and Ali al-Daraji, the editor of another of the newspapers, Al-Mustaqila.
It appeared to have been sparked when the Baghdad-based dailies published stories saying that a Shiite group lead by cleric Mahmoud al-Sarkhi was trying to dominate the holy city of Karbala.
The city, 90 kilometers (55 miles) south of Baghdad, is home to two revered Shiite shrines. In the last decade it has witnessed power struggles between Shiite militias.
Al-Sarkhi's group was not available for comment.
A group of men initially entered the office of the small Al-Parliman newspaper, demanding to meet the editor, the paper said in a statement posted on its website.
The men identified themselves as loyalists of al-Sarkhi and demanded to know why they published a report saying their leader was trying to take over communal Friday prayers at one of the holy shrines of Karbala.
The editor tried to mollify them, saying he believed the report was even-handed, the statement said.
It didn't satisfy the men.
As they left the editor's office, they appeared to signal to another group of men waiting outside. They smashed through the building's front door, shattering windows as they went through the building, Al-Parliman said.
They attacked reporters with batons, shoved computers onto the floor and tried to smash furniture, said the statement. They dragged one reporter to the building's roof and hurled him off, breaking both his legs, it said.
Editors al-Sheikh and al-Daraji offered similar accounts, except, they noted, the assailants also attacked them with knives.
Television footage following the attack on the Al-Mustaqila office showed computers strewn on the floor, the windows smashed. "The newspaper of lies, baseless claims and lies," was scrawled on a wall.
"It was so horrifying that we could not do anything," al-Daraji told The Associated Press.
A health official said five newspaper staffers were hospitalized, four with stab wounds. Al-Parliman said the fifth person was their staffer, pushed from the building's roof.
The health official spoke anonymously because he wasn't authorized to speak to the media.
Al-Sheikh said he also recognized the attackers as militant Shiites belonging to al-Sarkhi's group. Al-Daraji said they had run a similar story, but also published a response from the Shiite cleric's office.
It was not immediately possible to obtain comment from the fourth newspaper attacked, Al-Nas.
The four newspapers are considered modestly sized. The largest, al-Dustour, claims a run of 12,000 copies daily.
In response to the attacks Tuesday, blue-khaki clad police set up checkpoints through the middle-class Karradeh neighborhood, snarling traffic.
Iraq is ranked among the most dangerous places in the world for journalists, according to the New York-based Committee to Protect Journalists. At least 150 reporters and 54 support workers were killed in Iraq from the start of the U.S.-led invasion in March 2003 to the pullout of foreign troops in December 2011.
They did not have immediately updated figures for 2012.
Such attacks have been less common of late. The last major attack on reporters was the slaying of a television presenter Ghazwan Anas in July 2012, who worked for a channel in the predominantly Sunni northern city of Mosul.
The New York-based group said in a March statement that Iraq has never charged a person for killing a reporter. The "impunity rate . is the worst in the world. It is 100 percent," the statement said. "Even today, as Iraq has moved beyond conflict, authorities have shown no interest in investigating these murders."
Iraqi government spokesman Ali al-Moussawi condemned the attack. "Security forces have taken action and some of the (assailants) have been arrested and we are interrogating them," he said.
