BAGHDAD, Iraq (CNN) -- The Interior Ministry has removed a police brigade from the streets of Baghdad because of a brazen kidnapping this week of 26 people, a ministry spokesman said Wednesday.

Some Sunnis blame the abductions on Shiite death squads, which many people suspect are infiltrating Iraqi police units.

Interior Ministry spokesman, Brig. Gen. Abdul Karim Khalaf, said Wednesday the brigade was patrolled the southwestern neighborhood of Amil, where the kidnapping happened on Sunday.

At least 20 gunmen, several dressed like police commandos, parked in front of a meat processing plant, seized the workers and put them in three trucks before driving away.

U.S. Maj. Gen. William Caldwell announced the Iraqi police unit's recall earlier Wednesday and identified it as the 8th Brigade, 2nd National Police.

There is "clear evidence that there was some complicity in allowing death squad elements to move freely when, in fact, they were supposed to have been impeding their movement; that perhaps they did not respond as rapidly when reports were made," Caldwell said.

The brigade police officers "had not put their full allegiance commitment behind the government of Iraq," and instead, aligned with "some other elements outside" of the national police, he said.

The government lost "trust and confidence" in the unit because of "poor performances" and "alleged criminal wrongdoings," said Caldwell.

The brigade will get "anti-militia, anti-sectarian violence, and national unity training, both at the unit level and at the individual level," he said.

A triple bombing targeting Iraq's Ministry of Industry employees killed at least 12 people and wounded 70 others Wednesday in a mainly Christian neighborhood of Baghdad, police said.

Two bombs targeted ministry guards and another bomb targeted a ministry convoy, according to a Baghdad emergency police official.

A ministry spokesman said Industry Minister Fawzi al-Hariri was not present when the bombs went off in rapid succession as bodyguards were taking cars to a refueling site.

The convoy was traveling in the Camp Sara neighborhood and the attack also damaged part of a nearby building.

Bodies lay in the street next to the smoking wreckage of burning cars, according to The Associated Press.

Rescue workers piled corpses into an ambulance parked next to the crumbled facade of a building, while a policeman warned residents to leave for fear more bombs would explode, AP reported.

An increasingly common insurgent tactic is to detonate one bomb to draw rescue workers and onlookers, then to explode a second device to cause mass casualties.

One witness, who identified himself to AP only by his first name, Hamdi, said a roadside bomb went off first and people started to gather, then the second blast went off. "Then more people gathered and they were searching for their dead or missing relatives when the car bomb exploded," he told Associated Press Television News at the scene.

"Everybody knows this is a Christian neighborhood, they are neither Sunnis or Shiites, so why are they doing this to them?"

Meanwhile, security forces in the capital have found 22 bullet-riddled bodies in the past 24 hours. Some of the bodies showed signs of torture.
