In a major escalation of tensions in the Middle East, U.S. President Donald Trump announced that the United States has begun what he described as a “massive and ongoing operation” against Iran, following coordinated military action with Israel. The strikes hit multiple locations inside Iranian territory, including nuclear and missile infrastructure that Washington says poses a direct threat to U.S. national security.

In a video message posted on his social media platform Truth Social, Trump said early Saturday that American forces were undertaking major combat operations aimed at dismantling Iran’s missile capabilities, naval assets, and other military infrastructure. He framed the campaign as necessary to “defend the American people” and to prevent Iran from obtaining nuclear weapons or further threatening regional stability.

Trump accused Tehran of rebuffing diplomatic efforts and continuing to pursue programs that could eventually reach U.S. soil, and he warned Iranian military forces to lay down their arms or face “certain death.” He also appealed directly to the Iranian public, urging them to resist their government once the military phase of the operation concluded.

The operation represents a significant escalation in the Israel–Iran conflict, with explosions reported in several Iranian cities, including Tehran, and reports of Iranian retaliation with missile and drone attacks targeting Israel and U.S. positions in the region. Neighboring Iraq and other countries have closed their airspace as the situation continues to unfold.

Israel’s Prime Minister Benjamin Netanyahu praised the joint offensive, calling it a historic move to confront what he described as an “existential threat” from Iran’s regime. Meanwhile, Iranian officials have pledged retaliation and condemned the strikes, signaling the potential for broader conflict.

The announcement marks one of the most significant U.S. military actions in the Middle East in years, increasing concerns about the possibility of a prolonged conflict and its global repercussions. As events continue to evolve, world leaders and analysts are closely watching to see how Tehran, Washington, and allied nations respond in the coming days.
