BAGHDAD, Iraq - A U.S. helicopter crashed in a desert sandstorm in the early morning darkness Wednesday, killing the 30 Marines and one Navy sailor aboard. Six other troops died in insurgent ambushes in the deadliest day for Americans since the Iraq war began nearly two years ago.
Only days before Iraq's crucial elections Sunday, militants set off at least eight car bombings that killed 13 people and injured 40 others, including 11 Americans. The guerrillas also carried out a string of attacks nationwide against schools that will serve as polling centers.
In Washington, President Bush called on Iraqis to defy terrorism and go to the polls despite relentless insurgent attacks. He said it was a "very discouraging" day when the U.S. death toll for the war rose above 1,400.
The CH-53E Super Stallion was carrying personnel from the 1st Marine Division on a security mission in support of the election when it went down about 1:20 a.m. near the town of Rutbah, about 220 miles west of Baghdad, the military said.
The crash occurred during severe weather, but its cause was still under investigation, said Army Gen. John Abizaid, chief of U.S. Central Command. An Accuweather map showed sandstorms Wednesday in the western region of Iraq near the Jordanian border where the crash took place.
A search and rescue team was at the site. The victims were 30 Marines and one sailor, said Lt. Gen. John Sattler, the top Marine commander in Iraq - the most American service members to die in a single incident since the March 2003 invasion of Iraq.
All but three of the Marines had been based in Hawaii, according to Sen. Daniel Akaka, D-Hawaii.
The deadliest previous incident for U.S. troops was also a helicopter crash: a November 2003 collision of two Black Hawk helicopters that killed 17. Before Wednesday's bloodshed, the most Americans killed in one day came on the invasion's third day - March 23, 2003 - when 28 troops were killed during the U.S. military's drive to take Baghdad and topple Saddam Hussein.
The U.S. military has not seen such a high loss of life in one day in 15 years - since an explosion ripped through a gun turret on the USS Iowa during a training exercise in the Caribbean in April 1989, killing 47 sailors.
Iraqi security forces and civilians have borne the brunt of violence in Iraq, with bombings often killing scores of people at a time. More than 180 people were killed on March 2 during a string of suicide attacks at Shiite shrines in Karbala and Baghdad.
Violence has only increased ahead of Sunday's election, which will create a 275-member National Assembly and regional legislatures. Sunni Muslim extremists have threatened to sabotage the election, and many Sunni clerics have called for a boycott because of the presence of U.S. and other foreign troops.
The group calling itself al-Qaida in Iraq warned people to stay away from the polls, threatening attacks. "Oh people, be careful. Be careful not to be near the centers of infidelity and vice, the polling centers ... Don't blame us but blame yourselves" if harmed, a Web statement issued in the group's name said.
