Iran latest: US-Iran ceasefire remains shaky as both sides signal readiness to fight again

Signs of strain in the ceasefire between the U.S. and Iran seemed to arise over the weekend, ranging from a new threat by President Donald Trump to Iranian state TV presenters going on-air armed.

The Associated Press also reported that the U.S. may be coordinating with Israel for further attacks, citing information from two people familiar with the matter, one of whom is an Israeli officer. Prime Minister Benjamin Netanyahu told his Cabinet that "our eyes are open" in terms of Iran and "we are prepared for any scenario."

In a social media post early Sunday afternoon, Trump warned Iranian leaders that "the clock is ticking" and told them that they needed to act quickly or "there won’t be anything left of them."

In Iran, TV presenters went live on-air brandishing firearms. One of them claimed he was trained by a masked member of the country’s Revolutionary Guard and mimed shooting at a UAE flag. While on a different channel, the presenter had a weapon she said was sent to her, and declared, "From this platform I declare that I am ready to sacrifice my life for this country."
