More suspected rebels were detained, but leaders feared political talks would be affected.By Charles J. HanleyAssociated PressBAGHDAD - American and Iraqi troops pushing through a desolate area of Iraq's Sunni Arab heartland rounded up dozens more suspected insurgents, including the alleged killers of a television journalist, U.S. and Iraqi officials said yesterday.
The three-day-old sweep through villages 60 miles north of Baghdad stirred growing unease among leading Sunnis. One called it a needless "escalation" at a time of difficult negotiations over forming a government that would represent all of Iraq's communities.
In Baghdad, meanwhile, a dozen more bodies were found as a shadowy war of Shiite-Sunni reprisals went on. And Shiite Muslim pilgrims heading to the holy city of Karbala again came under attack, with a roadside bomb killing one and wounding five.
Reports of violence came from elsewhere as well: an oil-tanker driver shot dead 50 miles southeast of Baghdad, a tribal sheikh slain 30 miles west of the capital, a car bombing near a U.S. base in the northern city of Tal Afar in which the suicide driver was the only casualty.
