The Philippine military has released a report on this month's rescue mission that resulted in the deaths of an American and Filipino hostage.
The report says soldiers used extreme caution. But it does not conclude how the two captives died.
Elite Philippine troops ambushed rebels of the extremist Abu Sayyaf group June 7. American missionary Martin Burnham and a Filipino nurse were killed during the shooting. Burnham's wife, Gracia, was shot in the right thigh but was rescued.
The report says Martin Burnham was shot in the back, but it does not say who shot him.
The Philippine military is scheduled to further explain the eight-page report in a news conference tomorrow afternoon.
The Burnhams were part of a group of people kidnapped in May of last year from a southwestern beach resort.
