Two Iranian-backed militias in the Middle East are signaling their readiness to launch new attacks. The move seems to support Iran, which is concerned as a U.S. aircraft carrier has reached the region. On Monday, Yemen's Houthi rebels hinted at resuming attacks on Red Sea shipping. Iraq's Kataib Hezbollah also issued a threat on Sunday, warning of "total war" if Iran is targeted. The threats come as the USS Abraham Lincoln arrived in the region amidst Trump's threats to attack. The UAE announced it would not allow its territory to be used for military action against Iran, emphasizing dialogue and diplomacy.
