European markets higher despite heightened Middle East tensions; Temenos jumps 18% after review rejects Hindenburg claims

This is CNBC's live blog covering European markets.

European markets were higher on Monday amid heightened geopolitical tensions following Iran's massive drone and missile attack on Israel Saturday night.

The regional Stoxx 600 index was up 0.57% by 12:40 a.m. London time, with sectors trading in mixed territory. Industrial stocks led gains, rising 1.56%, while oil and gas fell 1.24% on rising risks in the Middle East.

Asia-Pacific markets slipped Monday as traders weighed the impact of the attack, with focus also on key economic data from China and Japan later in the week.

U.S. stock futures managed to tick higher Sunday as investors dealt with a multitude of issues, including Iran's attack and a spike in equity market volatility that sent the Dow Jones Industrial average to its worst week of the year last week.
