Gunmen attacked a bus carrying Baghdad airport employees to work this morning, and killed at at least four people, according to an airport employee.
"The bus was riddled with bullet holes. There was broken glass everywhere," said the employee. She said there were at least 25 people in the bus when it was fired on as it passed through a Baghdad suburb.
The bus was carrying administrative employees, she said.
Insurgents frequently attack buses transporting people to work at US-run bases or other installations seen to be under the control of US forces.
