BAGHDAD, Iraq -- A series of explosions along with the sound of low flying aircraft was heard early Wednesday, and the U.S. military said coalition missiles struck the Iraqi state-run television.

Smoke was seen next to the information ministry and the Iraqi TV building.

The signal from Iraqi Satellite TV, which broadcasts 24 hours a day outside Iraq, went off the air around 4:30 a.m., or 7:30 p.m. CST on Tuesday, according to monitors in Britain.

Iraq's domestic television service was not broadcasting at the time.

At the Pentagon, a U.S. military spokeswoman said coalition aircraft struck the Iraqi state-run television channel. Damage assessment was not complete, she told The Associated Press, speaking on condition of anonymity.

The coalition airstrikes targeted not only Iraqi television but also government communications and satellite links at several sites in the capital, U.S. military officials said. The strikes used Tomahawk cruise missiles fired from U.S. Navy ships and bombs dropped by coalition aircraft.

"These targets are key regime command and control assets," said Jim Wilkinson, a spokesman for U.S. Central Command.

On Tuesday, gray smoke from fuel fires and a swirling sandstorm enveloped Iraq's capital, where intermittent explosions once again rattled residents who embraced life's simple routines even as U.S.-led troops moved closer.

Garbage trucks rolled the streets picking refuse, which was piled high in some neighborhoods, while public transportation buses were running normally. Traffic was on the increase, and more stores and shops were open than at any time since the first missile hit Baghdad last week.

Fuel fires

The smoke hanging over the city came not from those missiles, but from fuel fires set by Baghdad authorities, an effort to obscure military targets in the city. Visibility was further hampered by a powerful sandstorm that seemed to cover everything in the city with a fine coat of sand.

U.S.-led troops were within 50 miles of the capital, setting up a seemingly inevitable fight for control of the historic city of 5 million residents. Iraqi Information Minister Mohammed Saeed al-Sahhaf said his countrymen were unshaken by that prospect.

The Iraqis "await surprises on how the American game of shock and awe will fail," al-Sahhaf said.

The wind in Baghdad became so wicked Tuesday that palm trees and traffic lights swayed madly, with security men and police hiding behind sandbags -- ordinarily military outposts -- in search of respite.

At the height of the sandstorm, the explosions that echoed through the capital for most of the day ceased.

More security and police officers were seen around the city than last week, and residents reported members of Saddam Hussein's feared intelligence agencies were also posted on the streets.

The bombing Tuesday was on the outskirts of the city, with its echoes easily audible in the heart of Baghdad. Some residents were busy digging new defensive trenches or expanding existing ones; some were dug in the courtyard of the Iraq museum, home to priceless antiques.

Iraqi state television went off the air for about 45 minutes after explosions were heard in the city Tuesday evening. There were unconfirmed reports in Baghdad that the outage followed a hit on a television transmission tower north of Baghdad in Abu Ghareib.

Television, like state radio, constantly played patriotic songs and messages of support from Iraqis for their president.

Tuesday's edition of Babil, a daily paper owned by Saddam's son Odai, featured back page photos of decapitated bodies that it said belonged to Iraqi civilians killed in bombing raids. A day earlier, all newspapers ran the text of Saddam's address to the nation on Page 1, accompanied by pictures of the Iraqi leader.
