'No comment' on attack in Iran: White House

STORY: The lack of comment is departure for a White House that routinely weighs in on the latest developments in Israel conflict.

Iran's foreign minister on Friday said Tehran was investigating an overnight attack on Iran, adding that so far a link to Israel had not been proven as he downplayed the strike.

Israel had said it would retaliate after a strike on April 13, the first ever direct attack on Israel by Iran, which caused no deaths after Israel and its allies shot down hundreds of missiles and drones.
