BAGHDAD (Reuters) - Iraq's military said eight policemenwere killed and more than 40 wounded in eastern Baghdad onTuesday as they tried to defuse rockets that had been preparedfor an attack.
The security forces were responding to rockets fired at twonearby army bases, one for U.S. and one for Iraqi forces, fromthe capital's Shi'ite Ubaidi district.
"The bomb disposal unit were trying to defuse eight rocketsin Ubaidi but they lost control and it exploded, killing eightand wounding 42," said Major-General Qassim Moussawi, spokesmanfor Iraq's military in Baghdad.
The U.S. military confirmed there had been an attack on oneof their bases but had no further details.
On Monday, five civilians were killed and 14 wounded whenrockets landed on a Sunni residential area near Baghdad'sinternational airport, in one of the capital's deadliest rocketattacks for months.
Police said they were fired from a neighbouring Shi'itearea.
The Iraqi military said on Saturday that attacks in Baghdadhad dropped by up to 80 percent thanks to a year-long securitycrackdown on al Qaeda militants and feuding Sunni Arab andShi'ite gunmen.
But the U.S. military has warned that "special groups", bywhich it means rogue elements in the Mehdi Army militia ofShi'ite cleric Moqtada al-Sadr, are still active and it hasbeen targeting them aggressively.
ROUNDUP
The U.S. military also said on Tuesday that Iraq's Ministryof Interior (MOI) had initiated plans to round up beggars andmentally handicapped people from Baghdad's streets to prevental Qaeda using them in suicide bomb attacks.
At the start of the month, two women set off explosives inpet markets in the capital, killing 99 people in what was thecapital's bloodiest attack since last April.
Although they have not given definitive proof, U.S. andIraqi officials said there was evidence that the women werementally impaired, had been duped by al Qaeda and thus wereprobably unaware of what they were doing.
"We are aware of the Ministry of Interior's efforts to tryand protect homeless and mentally impaired citizens frombecoming the unwitting victims of al Qaeda in Iraq," U.S.military spokesman Rear Admiral Greg Smith said in a statement.
"It is our understanding that the MOI intends to transferthese, the most vulnerable of Iraq's people, to the Ministry ofWork and Social Affairs."
Just over a week ago, U.S. troops raided a psychiatrichospital in Baghdad and arrested the hospital's director onsuspicion of involvement in the pet market bombings.
U.S. commanders say they believe al Qaeda in Iraq isresorting to new tactics after a crackdown on militants. Anextra 30,000 U.S. troops helped reduce violence and cut attacksby 60 percent across the country since last June, they say.
U.S forces are now targeting Sunni Islamist militants innorthern Iraq after they were forced from strongholds in thewest and around Baghdad after Sunni tribal sheikhs rebelledagainst them.
