The Pentagon is beefing up its presence in the Middle East, U.S. officials said Friday, as Israel braces for Iran to retaliate for a strike near its embassy in Syria. President Biden, in remarks to reporters Friday, warned Iran not to strike but added that he expected the attack would come “sooner than later.” Israel has not publicly claimed responsibility for the attack in Syria that killed two senior members of Iran’s Revolutionary Guard. U.S. officials have not said whether the potential retaliation would come from Iran directly or from an Iran-backed group.
