KEY POINTS:
BAGHDAD - US helicopters attacked gunmen holed up inside high-rise buildings in Baghdad today in what the US military said was an operation to regain control of a major street cutting through the heart of the city.
Thirty insurgents were killed and 35 detained during day-long gunbattles in the area, Iraq's Defence Ministry said.
The US military said one US soldier had been killed in central Baghdad but would not confirm whether it was during the clashes.
The fighting came a day after US President George W Bush told a joint session of the US Congress in his annual State of the Union address that America dared not fail in Iraq and called on lawmakers to support his plan to send more troops.
US and Iraqi troops backed by Apache attack helicopters and armoured Stryker vehicles firing their heavy machine guns fought militants in Haifa Street in a battle that began around daybreak, US military spokesman Major Steven Lamb said.
He said US troops also fired mortars after coming under machinegun, mortar and rocket-propelled grenade attack during the operation to restore Iraqi security control of the Sunni insurgent stronghold, which lies within 2 km of the Green Zone, the heavily fortified compound housing Iraq's government.
"A lot has been coming from high-rise buildings. We are firing at terrorists in those buildings," Lamb told Reuters.
He had no details on casualties, but a local resident said he had counted six bodies, all men, one of whom had a rifle lying next to him.
A local journalist said he helped transport 37 wounded people to hospital, including women and children, in three ambulances that managed to get through the security cordon.
Haifa Street, a long thoroughfare of high-rise buildings built by Saddam Hussein in the early 1980s, runs along the west bank of the Tigris River that cuts through the capital.
While the area was too dangerous for journalists to venture into, helicopters could be seen circling overhead amid the repetitive dull thud of mortar fire. US and Iraqi forces said they killed more than 100 militants there earlier this month.
The Iraqi government said then the area was riddled with "terrorist hideouts" and said it had captured many foreign Arab fighters linked to al Qaeda in that operation two weeks ago.
The US military said Wednesday's mission was "not an operation designed solely to target Sunni insurgents, but rather aimed at rapidly isolating all active insurgents and gaining control of this key central Baghdad location".
Battling growing Sunni-Shi'ite violence, Shi'ite Prime Minister Nuri al-Maliki has announced a major security plan for Baghdad, vowing to crack down on violence on all sides. But his aides stress it has not yet started.
Bush has said he is sending 21,500 more troops to Iraq, most to bolster the new crackdown, despite fierce opposition from Democrats who now control Congress, resistance within his own party and public scepticism.
"On this day, at this hour, it is still within our power to shape the outcome of the battle. Let us find our resolve, and turn events toward victory," Bush told Congress.
The US military said two US Marines were killed in combat on Tuesday in western Anbar region, heartland of the Sunni insurgency, where Bush plans to send 4,500 fresh troops.
Wednesday's Haifa Street operation was condemned by the Muslim Scholars Association, a leading Sunni clerics group, that called it "a campaign of genocide".
Security sources said a helicopter owned by Blackwater, a US security company that crashed during clashes in the area yesterday was forced down after the pilot was shot dead.
Three others on board the aircraft, which had been guarding a diplomatic convoy on the ground, may have been shot on landing, they said, although other reports suggested they died when the aircraft crashed. A fifth person on a second Blackwater helicopter was also shot dead.
US ambassador Zalmay Khalilzad paid his condolences to the security contractors, who helped protect US embassy personnel, saying he had known them personally.
Gunmen opened fire on the motorcade of Iraq's higher education minister, Abd Dhiab al-Ajili, on a highway in southern Baghdad on Wednesday, killing one of his guards and seriously wounding another, the minister told Reuters.
