U.S. deploys aircraft carrier as Iran warns against attack

U.S. aircraft carrier deployed in the Middle East amid Iran's warning of retaliation against potential military action.

A U.S. naval strike group led by an aircraft carrier has deployed to Middle Eastern waters, the United States said on Monday (January 26, 2026), as Tehran warned it was ready to hit back at any American attack launched in response to a crackdown on anti-government protests.

A U.S.-based rights group said on Monday (January 26) that it had confirmed the deaths of nearly 6,000 people in the wave of protests suppressed by Iran's security forces, but emphasised the actual toll could be several times higher.

The protests started in late December, driven by economic grievances, but turned into a mass movement against the Islamic republic, with huge street demonstrations for several days from January 8.

But rights groups have accused authorities of quelling the movement with unprecedented violence, shooting into crowds of protesters under the cover of an internet shutdown that has now lasted 18 days — the longest Iran has ever imposed.

U.S. President Donald Trump has previously threatened to intervene, saying last week that Washington was sending a "massive fleet" to the region "just in case".
