Coalition troops spent Christmas Day under fire amid the most widespread series of rocket and mortar attacks since the Dec. 13 capture of Saddam Hussein.

Hotels, foreign embassies, coalition headquarters and patrols were targeted by bombs that killed four U.S. soldiers and six Iraqi civilians.

At sunrise, a volley of more than a dozen rockets rained down on the Iranian and Turkish embassies, shattering windows and blowing holes in the mission walls. Reported damage was limited.

Other rockets hit a residential building next to the German embassy and skimmed by the Iraqi Interior Ministry building to land in the street.

One woman was injured in a nearby apartment complex.

The Sheraton Ishtar Hotel in Baghdad was hit in two separate incidents.

The hotel is known for housing Westerners, including reporters and civilian contractors, and came under attack last month by rockets fired from donkey-pulled carts in the street.

Fox News journalists staying at the heavily guarded central Baghdad hotel yesterday reported feeling a massive concussion and spotted a hole in the roof near the neon lettering that spells out “Sheraton.”

“We’ve been informed that two Iraqi individuals in two cars fired a mortar round at the hotel. Security guards fired at them as they fled,” Pvt. Michael Williams told Reuters.

“This one was close, very close,” Fox producer Scott Heidler said. “The building shook and you could feel the sucking of air when an explosion happens. You could feel the air move right around you.”

Early this morning a grenade lobbed into the atrium exploded leaving debris and shattered glass in its wake.

Hotel officials reported no casualties.

Another rocket hit the Bourj al-Hayat Hotel, also frequented by Westerners.

Soldiers investigating the attacks found leaflets warning Iraqis to stay home, U.S. forces to leave the country and Iraqi police to stop cooperating with foreign occupiers.

“This is a regular day for us,” an unfazed Army 1st Lt. Kurt Muniz told Reuters as he led several soldiers on a foot patrol in the area.

“I guess they think security’s going to be downgraded because of the holiday,” he told Fox. “If they want to bring it, I say bring it on.”

The bombings come amid intelligence that Saddam loyalists planned a wave of spectacular attacks over the Christmas holiday.

Fox reports military officials believe as many as 14 terrorist cells are active in Baghdad.
