The military has suffered its deadliest day so far since the Iraq invasion began. On Wednesday a military helicopter crashed near the Jordanian border killing 30 Marines and one Navy sailor. Another six soldiers died in combat bringing the day’s total death toll to 37. President Bush described Wednesday as a “very discouraging day.” The U.S. has now lost over 1,400 soldiers in Iraq. The cause of the helicopter crash is still unknown. It occurred during a sandstorm but investigators have not determined the actual cause. The Marines were being transported to take part in an effort to provide security for Sunday’s national election.
