Baghdad, Iraq (CNN) -- Gunmen intercepted a vehicle carrying salaries of Iraqi government employees in western Baghdad and made off with nearly $600,000, police officials told CNN on Sunday.
The robbers attacked the vehicle a few hundred meters from a local bank, where it had been loaded with money, police said.
Police officials said it appeared that the gunmen, who stole about 700 million Iraqi dinars, were monitoring the truck and may have had assistance from someone working at the bank or government employees.
Iraqi security forces are investigating the incident. Police said no one was injured in the heist.
Authorities have said they believe insurgents have used similar recent robberies to fund their military operations.
