(Alliance News) - Stock prices in London opened lower on Wednesday as renewed military escalation between the US and Iran lifted oil prices and unsettled investors, outweighing gains for energy stocks.
The FTSE 100 index opened down 83.63 points, 0.8%, at 10,583.68. The FTSE 250 was down 150.50 points, 0.6%, at 23,228.68, and the AIM all-share was down 0.95 points, 0.1%, at 768.23.

Markets turned risk-averse after the US and Iran exchanged fresh military strikes, raising fears that the fragile ceasefire between the two countries could unravel.
US Central Command said it had carried out "powerful strikes against Iran" on Tuesday evening after accusing Tehran of attacking three commercial vessels transiting the Strait of Hormuz this week, calling the incidents "a clear and dangerous violation" of the ceasefire.
The Pentagon later said US forces had struck around 80 Iranian military targets, hours after Washington revoked a general licence allowing sales of Iranian oil.
Oil prices responded to the renewed tensions. Brent crude traded at USD75.80 a barrel early Wednesday, up from USD73.88 late Tuesday.
Geopolitics also dominated the Nato summit in Ankara, where US President Donald Trump again questioned America's long-term military commitment to Europe.
Trump said he could withdraw all US troops from Europe and renewed calls for the US to take control of Greenland, remarks that threatened to reignite tensions with European allies.
Nato Secretary General Mark Rutte sought to reassure members, insisting the US remained "completely committed" to the alliance despite Trump's latest comments.
