Iran warned the U.S. and Israel against renewing their attacks on Tehran this week as President Donald Trump's administration faces fresh challenges on the Iran war from Democrats in Congress.

Iran says its ties with Russia are stronger than ever after a visit by Putin's top envoy, challenging Trump's assertion that Moscow isn't helping Iran in the war.

Mohsen Rezaei, secretary of Iran's Supreme National Security Council, said the country's military has prepared a response to any new attacks.

A coalition of armed rebel groups is stepping up attacks against Iranian regime forces in the country's volatile southeast, raising questions about Tehran's grip on the region.

(JTA) — President Donald Trump and Israeli Prime Minister Benjamin Netanyahu have said they don’t want to see a renewal of the war against Iran – but they are issuing stark public warnings to Tehran that could bring the simmering conflict to a boil.

Iran has deliberately prolonged talks with the US to try to weaken Donald Trump politically ahead of November's US midterm elections, senior officials say, while fears of renewed military action and deep distrust of Washington have reinforced Tehran's reluctance to strike a quick deal to end the war.

Israel has heightened its readiness for a possible regional escalation, even as the prevailing assessment among Israeli officials is that neither Jerusalem nor Washington will initiate strikes against Iran before the upcoming Israeli and American elections.

A fire erupted and cars were ablaze following an Iranian attack in southern Israel on Friday. Earlier on Friday, the Israeli army said that "sirens sounded in several areas across Israel following the identification of missiles launched from Iran” towards Israel.

The U.S. secretary of state listed conflicts across the Middle East, which he maintained are instigated directly by Tehran or its proxies.
