JERUSALEM — Iran threatened Wednesday to “decisively respond” to any U.S. attack on the Islamic Republic following President Joe Biden’s linking of Tehran to the killing of three U.S. soldiers at a military base in Jordan.

       The U.S. has signaled it is preparing for retaliatory strikes in the Mideast in the wake of the Sunday drone attack that also wounded at least 40 troops at Tower 22, a secretive base in northeastern Jordan that’s been crucial to the American presence in neighboring Syria.

       Any additional American strikes could further inflame a region already roiled by Israel’s ongoing war on Hamas in the Gaza Strip. The war began with Hamas attacking Israel on Oct. 7, killing some 1,200 people and taking about 250 hostage. Since then, Israel has killed more than 26,000 Palestinians and displaced nearly 2 million others from their homes, arousing anger throughout the Muslim world.
