LONDON — European stocks started the new trading week in negative territory on Monday as investors react to the latest developments in the U.S.-Iran war.

The pan-European Stoxx 600 was 0.7% lower shortly after 8:00 a.m. in London (3:00 a.m. E.T.).

The U.K.'s FTSE 100 index was 0.2% lower, Germany's DAX 0.5% lower, and France's CAC 40 down 1%, as Italy's FTSE MIB slumped more than 2%.

Energy names were up 0.7% in early trade, as oil prices rose, while media stocks added 0.3%. All other European sectors slipped into the red.

European stocks followed their Asia-Pacific counterparts lower on Monday after U.S. President Donald Trump warned Iran to "get moving, FAST" to agree the terms of a peace deal.

In a post on Truth Social, Trump on Sunday said "the clock is ticking" for Iran and warned there "won't be anything left" if action was not taken soon, adding that "time is of the essence."

The President did not elaborate, but the warning comes as negotiations between the U.S. and Iran appear to be deadlocked.

Oil prices rose overnight following the comments, with international benchmark Brent crude futures for July gaining 1.57% to trade at $110.97 per barrel. U.S. West Texas Intermediate futures for June advanced 1.89% to $107.41 per barrel.
