The Iranian Armed Forces Central Headquarters spokesperson warned Saturday it would consider military assistance to Israel via sea or air "by any country" as an act of aggression.

Israel has lost a "significant part" of its defensive capabilities as a result of Iranian missile strikes, and is facing ammunition shortages despite considerable military support from the United States, the spokesperson said.

Meanwhile, reports emerged of the US moving heavy B-2 stealth bombers to Guam, in anticipation of potential strikes on Iran's nuclear facilities.
