May 13 (Bloomberg) -- President Barack Obama has reversed his stance and is seeking to block release of photographs that show the treatment of prisoners in Iraq and Afghanistan by U.S. personnel, White House press secretary Robert Gibbs said.

The president “did not feel comfortable with release of the photos” which military officials said might endanger troops, Gibbs said.

A federal appeals court ordered the release in connection with a suit.
