What is Tower 22, the Jordan-based US outpost targeted in a drone strike?

The United States military announced on Sunday that three US soldiers were killed and at least 34 were wounded in a drone attack targeting Tower 22, a remote logistics outpost near the Jordan-Syrian border. The attack has elicited a strong reaction from Washington with President Joe Biden pledging to hold the attackers to account. The Islamic Resistance in Iraq, an umbrella group of Iran-backed armed groups in the region, claimed the attacks, saying it was in response to US support to Israel's war on Gaza, which has killed more than 26,000 people. Tower 22, which houses a small US logistics outpost, is located in Jordan's northeast close to the borders with Iraq and Syria. Public information about the outpost is limited.
