BAGHDAD, Iraq - The Shiite prime minister promised Sunday to reshuffle his Cabinet after calling lawmakers disloyal and blaming Sunni Muslims for raging sectarian violence that claimed at least 159 more lives, including 35 men blown apart while waiting to join Iraq's police force.

Among the unusually high number of dead were 50 bodies found behind a regional electrical company in Baqouba, 35 miles northeast of Baghdad, and 25 others found scattered throughout the capital. Three U.S. troops were reported killed, as were four British service members.

Also Sunday, the country's Sunni defense minister challenged Prime Minister Nouri al-Maliki's contention that the U.S. military should quickly pull back into bases and let the Iraqi army take control of security countrywide.
