Oil rises after U.S. strikes in Iran, markets turn cautious

New U.S. strikes inside Iran weakened expectations that Washington and Tehran could soon reach an agreement, pushing oil prices higher and adding to market jitters. Brent crude rose to about $97 a barrel, while U.S. crude posted a more modest gain. Iranian officials were said to be taking part in talks in Doha over a possible deal, with the reopening of the Strait of Hormuz about 30 days after any agreement also under discussion. Concerns over the broader impact on the global economy kept stock markets mixed. The dollar held relatively steady as investors sought safe havens.
