An Iraqi group said Wednesday it had taken six hostages - three Indians, two Kenyans and an Egyptian - and would behead them if their countries did not immediately announce their intention to withdraw their citizens from Iraq. In a statement given to The Associated Press, the group, calling itself "The Holders of the Black Flags," said it had abducted the six truckers and would behead one of them every 72 hours if their nations did not pull out of Iraq and the company they work for did not close its branch in Iraq. "We have warned all the countries, companies, businessmen and truck drivers that those who deal with American cowboy occupiers will be targeted by the fires of the Mujahedeen," the statement said. "Here you are once again transporting, goods, weapons and military equipment that backs the U.S. Army." From the statement, the trucking company that employed the men appeared to be based in Kuwait. Earlier in the day, two people were killed and four wounded when a missile hit the seventh floor of a hospital in Baghdad, Sky News reported. "Two patients were killed and four others including patients and staff were seriously wounded when a missile hit the seventh floor this afternoon," said doctor Amir Mokhtar at Adnan Khairallah hospital. The attack came soon after a car bomb killed four people and injured several more in the Iraqi capital. The blast took place in a southern residential district of Baghdad. Some houses in the area were blackened by the blast and at least three cars were damaged, Reuters reported. **PHOTO CAPTION*** Three kidnappers carrying automatic weapons stand in front of six hostages at an undisclosed location in Iraq on this picture handed to the Associated Press on Wednesday July 21, 2004.
