This is CNBC's live blog covering European markets.

European markets dipped Monday as investors assessed the impact of geopolitical turmoil in the Middle East, after Palestinian militant group Hamas launched a large-scale attack on Israel on Saturday.

The Stoxx 600 index closed 0.3% lower, with travel and leisure stocks down 2.4% and retail stocks dipping 1.9%. Oil and gas stocks were higher by 2.9% as crude oil prices surged.

Hundreds of people have died in the conflict between Hamas militants and Israeli forces.

Oil prices jumped 4% overnight and U.S. stocks were lower Monday as the violence adds geopolitical risk to already fragile markets dealing with inflation and surging interest rates.

The Israeli-Palestinian conflict escalated to a full-blown war on Saturday after Hamas staged an invasion, by which Israel was seemingly caught off guard. Israeli Prime Minister Benjamin Netanyahu asserted that Hamas "will pay a price it has never known before."

Energean shares plummet 20% after Israel attack

Shares of oil and gas company Energean plummeted more than 20% after it announced that production, supply and work offshore would continue after the attack on Israel. The company said that the area where it operates, in the northern region of Israel, is not currently under attack.

Energean is listed on both London and Tel Aviv's stock exchanges.

While Energean fell to the bottom of the Stoxx 600 index, fuel-related worries hit shares of U.S. cruise operators Norwegian Cruise Line Holdings, Carnival and Royal Caribbean Group, which were each down between 4.1% and 6.2%.
