European shares hit their highest in more than two months on Monday, buoyed by signs Iran and the U.S. were negotiating an end to their conflict, easing concerns about inflation and a global economic slowdown.
The pan-European STOXX 600 (.STOXX) was up 0.67% at 629.28 points at 0818 GMT, just shy of a record high touched in late February, before the Middle East war erupted.
Most sectors gained, led by banks (.SX7E) with a 1.9% jump. Airlines also advanced, with Lufthansa (LHAG.DE) and Air France KLM (AIRF.PA) up 3.7% and 7.5%, respectively, as Brent Crude slid 4.7% to $98 a barrel.

Clarity remains limited on key sticking points, including Iran's nuclear programme.
"Contentious issues like Iran's nuclear plans, its uranium enrichment and the control of the Strait of Hormuz remain potential obstacles," said Kyle Rodda, senior financial market analyst at Capital.com.

Among individual stocks, Delivery Hero <DHER.DE> jumped 11% to an 18-month high after a report said Uber's <UBER.N> board met on Saturday to discuss raising its offer for the German food-delivery group, following a rejection by a major shareholder of a bid valuing the company at more than 11.5 billion euros ($13.4 billion).
Meanwhile, tensions escalated in Ukraine as Russia pounded Kyiv and surrounding areas. Defence stocks (.SXPARO) gained 1.5%.
Energy stocks (.SXEP) underperformed, tracking the slide in crude prices.
