WASHINGTON (AP) — The Pentagon is considering sending several thousand additional troops to the Middle East to help deter Iranian aggression, amid reports of escalating violence in Iran and continued meddling by Tehran in Iraq, Syria and other parts of the region. John Rood, defense undersecretary for policy, told senators Thursday that Defense Secretary Mark Esper “intends to make changes” to the number of troops deployed in the region. Other officials said options under consideration could send between 5,000 and 7,000 troops to the Middle East, but they all stressed that there have been no final decisions yet. The officials spoke on condition of anonymity to discuss internal deliberations. The troop deliberations follow several decisions since spring to beef up the U.S. presence in the Middle East because of a series of maritime attacks and bombings in Saudi Arabia that the U.S. and others have blamed on Iran.
