Explosions rock Tehran as US official warns 'biggest bombing' of war is coming Explosions sent up dark plumes of smoke over Tehran on Saturday as the conflict escalated, with the United States warning of an impending "biggest bombing campaign" of the war. Iranian retaliatory missile strikes targeted Israel, while sirens blared across Bahrain and Saudi Arabia as the fighting expanded beyond regional borders. The violence, which has already claimed lives and caused widespread destruction, shows no signs of abating, with the Trump administration approving a new $151 million arms sale to Israel amid calls for Iran's "unconditional surrender." The attacks on Tehran, which included strikes on military infrastructure and leadership targets, were met with Iranian missile fire directed at Israeli cities. In Jerusalem, loud booms echoed as incoming Iranian missiles prompted residents to seek shelter. The conflict has also drawn in Gulf allies, with Saudi Arabia reporting the destruction of drones aimed at its Shaybah oil field and the interception of a ballistic missile near a US military base. US Treasury Secretary Scott Bessent warned in a televised interview that the "biggest bombing campaign" of the war was yet to come, reflecting the administration's escalating stance. Israel confirmed it had bombed an underground bunker believed to be a key Iranian leadership facility, though details of the operation remain scarce. Meanwhile, US President Donald Trump reiterated his refusal to negotiate with Iran without its "unconditional surrender," vowing to support the selection of a "great and acceptable leader" to replace the late Supreme Leader Ayatollah Ali Khamenei. Iranian President Masoud Pezeshkian addressed the crisis on social media, acknowledging ongoing mediation efforts but offering no specifics.#iran #israel #bahrain #saudi_arabia #scott_bessent
