WASHINGTON, Sept 29 (Reuters) - The U.S. military said on Sunday it was increasing its air support capabilities in the Middle East and putting troops on a heightened readiness to deploy to the region as it warned Iran against expanding the ongoing conflict.

The announcement came two days after President Joe Biden directed the Pentagon to adjust U.S. force posture in the Middle East amid intensifying concern that Israel’s killing of the leader of Iran-backed Hezbollah could prompt Tehran to retaliate.

“The United States is determined to prevent Iran and Iranian-backed partners and proxies from exploiting the situation or expanding the conflict,” Pentagon spokesperson Major General Patrick Ryder said in a statement.
