June 13 (Reuters) - U.S. stock index futures dropped on Friday after Israel's military strike on Iran's nuclear facilities escalated tensions in the oil-rich Middle East and battered risk sentiment across global markets.
Israel has warned that the widescale strikes were the start of a prolonged operation to prevent Tehran from building an atomic weapon. Iran has promised a harsh response.
An escalation in the conflict can "drag the U.S. into it, in which case, we would expect that global oil and gas supply will be disrupted for longer," analysts at Panmure Liberum said in a note.
Oil prices surged nearly 9% and U.S. energy stocks rose in tandem, with Chevron (CVX.N), and Exxon (XOM.N), advancing 3.1% and 3.5% in premarket trading.
Washington said it had no part in the operation, but President Donald Trump suggested Iran had brought the attack on itself by resisting U.S. demands to restrict its nuclear programme. Officials from both countries were due to meet in Oman on Sunday for a planned sixth round of nuclear talks.
Trump also urged Iran to make a deal, saying "the next already planned attacks" will be "even more brutal".
