Iran tells US it’s not seeking war but ‘unilateral restraint’ is over

At least nine killed in Israeli air attack on central Beirut, as fights in southern Lebanon intensify.

This is merely a bullet point on the main article, but seems more-significant to me than the article’s main title, and has now been cited on a number of other news sites:

Iranian source tells Al Jazeera Iran sent a message to the US via Qatar saying that it does not seek regional war but adding that “the phase of unilateral self-restraint has ended”. It also warned any Israeli attack would be met with an “unconventional response” that includes targeting Israeli infrastructure.
