European stocks opened lower on Wednesday after Iran fired rockets on Iraqi airbases housing U.S. troops.

The pan-European Stoxx 600 slid 0.4% at the start of the trading session, chemicals shedding 0.8% to lead losses as all sectors except oil and gas entered negative territory.

Tehran retaliated to Washington's killing of its top military commander late Tuesday, launching more than a dozen ballistic missiles targeted at U.S. military forces in Iraq. It was not immediately clear whether any U.S. service members were harmed in the attacks.
