Global stock markets experienced a mixed trading session on Thursday, accompanied by a slip in oil prices, as conflict in the Middle East intensified with fresh attacks exchanged between Iran and the United States. U.S. stock futures remained largely unchanged.

The United States conducted further airstrikes targeting Iran, prompting a retaliatory response from Iran with attacks directed at Bahrain, Kuwait, and Qatar. This escalation follows U.S. President Donald Trump's declaration that a temporary ceasefire was "over." The prospects for a stable resolution remain uncertain, with high-level talks reportedly underway to salvage an interim agreement to end the conflict, according to a regional intelligence official involved in mediation efforts.

In early European trading, the FTSE 100 in Britain fell 0.6% to 10,422.75. France's CAC 40 saw a modest increase of 0.3% to 8,280.05, while Germany's DAX traded 0.3% higher at 24,963.05.
