Yemen rebels threaten new Red Sea attack as US aircraft carrier heads toward Iran

DUBAI, United Arab Emirates — Yemen's Iranian-backed Houthi rebels threatened new attacks on ships traveling through the Red Sea corridor, likely trying to back Iran as it worried Monday about an approaching U.S. aircraft carrier after President Donald Trump threatened military action over its crackdown on nationwide protests.

A short video by the Houthis included previously published images of a ship on fire, with the caption: ''Soon.'' The rebels did not elaborate, but their campaign in the Red Sea saw over 100 ships attacked as part of a campaign the Houthis said pressured Israel over its war against Hamas in the Gaza Strip. The Houthis halted their fire after a ceasefire in the conflict, though they've repeatedly warned they could resume fire if needed.

The Houthi threat come as the aircraft carrier USS Abraham Lincoln and other guided missile destroyers with it move toward the region. Trump has said the ships are being moved ''just in case'' he decides to take action against Iran. Trump already has laid out two red lines for attack — the killing of peaceful protesters and Tehran conducting mass executions of those it has arrested in a massive crackdown over the demonstrations.

Iran renews threats and limits smaller flights

Iranian Defense Ministry spokesperson Gen. Reza Talaei-Nik renewed warnings Monday to both Israel and the U.S. over any possible attack, saying it would "be met with a response that is more painful and more decisive than in the past.'' Iranian state television quoted Talaei-Nik as adding that threats from the two countries required Iran ''to maintain full and comprehensive preparedness.''

Iran over the weekend unveiled a new banner in Enghelab Square threatening the Lincoln, showing an aircraft carrier strewn with bodies and streaked with blood with the warning: ''If you sow the wind, you will reap the whirlwind.'' However, Iran is still reeling from a 12-day war launched by Israel in June that saw its air defense systems broadly destroyed and top military leaders killed, as well as its nuclear enrichment sites bombed by the U.S.

As a sign of concern over its airspace, Iran issued a notice to pilots Sunday that banned small private aircraft from flying in the country, with carveouts for the oil industry and emergency medical flights.

Death toll rises from protest crackdown

The protests in Iran began on Dec. 28, sparked by the fall of the Iranian currency, the rial, and quickly spread across the country. They were met by a violent crackdown by Iran's theocracy, the scale of which is only starting to become clear as the country has faced more than two-week internet blackout — the most comprehensive in the nation's history.

The U.S.-based Human Rights Activists News Agency on Sunday put the death toll at 5,848, with the number expected to increase. It says more than 41,280 people have been arrested.

The group's figures have been accurate in previous unrest and rely on a network of activists in Iran to verify deaths. That death toll exceeds that of any other round of protest or unrest there in decades, and recalls the chaos surrounding Iran's 1979 Islamic Revolution. The Associated Press has not been able to independently verify the toll.
