Tehran: A day after US President Joe Biden vowed to take “revenge” following a deadly attack on American troops in Jordan, Iran, on Wednesday, threatened to “decisively respond” to any US attack on the Islamic Republic. Earlier, Biden linked Tehran to the killing of three US soldiers at a military base in Jordan. The US has signalled it is preparing for retaliatory strikes in the Mideast in the wake of the Sunday drone attack that also injured at least 40 troops at Tower 22, a secretive base in northeastern Jordan that’s been crucial to the American presence in neighbouring Syria.Tehran: A day after US President Joe Biden vowed to take “revenge” following a deadly attack on American troops in Jordan, Iran, on Wednesday, threatened to “decisively respond” to any US attack on the Islamic Republic.
