Pentagon boosting forces in the Middle East following a series of attacks on American and allied troops in Iraq, Syria, and the Red Sea.

Nine hundred service members are or will be deploying to the Middle East as the United States seeks to respond to attacks on its forces and to prevent the Israel-Hamas War from spiraling into a regional conflict.

Some of those troops were previously given prepare-to-deploy orders but others were not, according to Pentagon spokesperson Brig. Gen. Pat Ryder.

“These include forces that have been on prepare-to-deploy orders and which are deploying from the continental United States,” Gen. Ryder said to reporters on Oct. 26.
