TOKYO (Reuters) -Stocks dived in early Asian trade on Friday, led by a selloff in U.S. futures while safe havens like gold and the Swiss franc climbed along with crude oil prices on news that Israel had conducted a military strike on Iran.

U.S. S&P e-mini futures slumped 1.1% as of 0018 GMT and Nasdaq futures skidded 1.3%.

Japan's Nikkei lost 1% and South Korea's KOSPI slipped 0.6%. Most other regional markets had yet to open.

Brent crude jumped about 5% to $72.76 per barrel. Gold added 0.8% to $3,410 per ounce.

The Swiss franc gained about 0.5% to 0.8060 per U.S. dollar, and fellow safe haven the yen appreciated 0.4% to 142.89 per dollar.

Israel has begun carrying out strikes on Iran, two U.S. officials told Reuters on Thursday, adding there was no U.S. assistance or involvement in the operation.
