Jordan is becoming a new focal point in the U.S.-Iran war, writes The New York Times.

Four Iranian attacks over five days targeted American troops in Jordan, U.S. officials said, including one on Friday that killed two soldiers and left another service member missing.

Taken together, these attacks have wounded dozens of American service members and damaged several helicopters.

The barrage of attacks and the losses they caused indicate that Iranian forces not only still have a sufficient stockpile of missiles, but have also become more skilled at evading American air defense systems, U.S. officials said.

Jordan, which hosts major American air bases, took on greater importance in the lead-up to and early days of the war as the Pentagon relocated some troops from Bahrain, the United Arab Emirates, and Qatar to relatively safer locations in Jordan and Israel. The country’s role in U.S. operations has only grown as other American allies in the region have limited Washington’s ability to station troops and conduct flights over their territories, U.S. officials said.

In early July, Iran expanded the scope of its attacks in the region, including Jordan for the first time since Tehran and Washington signed a ceasefire agreement in June.

U.S. officials provided a brief overview of the last five days of Iranian attacks on Jordan, which the Pentagon has not yet discussed publicly in detail.

The first attack on American troops in Jordan struck a residential compound at King Faisal Air Base, wounding up to five American service members, they said. A second missile hit a base in eastern Jordan where American Black Hawk helicopters were stationed, damaging a significant number of them.

In addition, Iranian missiles struck Jordan’s Muwaffaq Salti Air Base in Azraq — the same base where U.S. service members were killed on Friday.

In the previous strike, about 20 American service members were injured while trying to take shelter in bunkers. No one was killed in that attack.
