Ayatollah threatens Israel, US with 'a crushing response'

Iran's supreme leader on Saturday threatened Israel and the US with “a crushing response” over attacks on Iran and its allies.

Ayatollah Ali Khamenei spoke as Iranian officials are increasingly threatening to launch yet another strike against Israel after its October 26 attack on the Islamic Republic that targeted military bases and other locations and killed at least five people.

Any further attacks from either side could engulf the wider Middle East, already teetering over the Israel-Hamas war in the Gaza Strip and Israel's ground invasion of Lebanon, into a wider regional conflict just ahead of the US presidential election this Tuesday.

“The enemies, whether the Zionist regime or the United States of America, will definitely receive a crushing response to what they are doing to Iran and the Iranian nation and to the resistance front," Khamenei said in video released by Iranian state media.

The supreme leader did not elaborate on the timing of the threatened attack, nor the scope. The US military operates on bases throughout the Middle East, with some troops now manning a Terminal High Altitude Area Defence, or THAAD, battery in Israel.

The USS Abraham Lincoln aircraft carrier likely is in the Arabian Sea, while Pentagon press secretary Maj Gen Pat Ryder said on Friday that more destroyers, fighter squadrons, tankers and B-52 long-range bombers would be coming to the region to deter Iran and its militant allies. Early on Sunday, the US military's Central Command said B-52s from Minot Air Force Base's 5th Bomb Wing arrived in the Middle East, without elaborating.

The 85-year-old Khamenei had struck a more cautious approach in earlier remarks, saying officials would weigh Iran's response and that Israel's attack “should not be exaggerated nor downplayed”. Iran has launched two major direct attacks on Israel, in April and October.
