NEW YORK (Reuters) -Oil prices dropped nearly 2% on Wednesday, eating into the previous day's gains as investors monitored developments in the Red Sea, where shippers are returning despite further attacks on Tuesday.
Brent crude futures settled down $1.42, or 1.8%, at $79.65 a barrel. U.S. West Texas Intermediate crude fell $1.46, or 1.9%, to $74.11.
Danish shipping company Maersk said it has scheduled several dozen container vessels to travel via the Suez Canal and Red Sea in the coming weeks after calling a temporary halt to those routes this month after attacks by Yemen's Iran-backed Houthi militia.
France's CMA CGM also said it was resuming passage through the Red Sea after deployment of a multinational task force to the region.
"I think we have to wait and see whether the increased naval patrols and rerouting of ships lead to a decline in attacks," said Callum Macpherson, head of commodities at Investec.
Both the Brent and WTI benchmarks settled more than 2% higher in the previous session as the latest attacks on ships in the Red Sea prompted fears of shipping disruption.
The prospect of a prolonged Israeli military campaign in Gaza remained a major driver of market sentiment.
Israeli forces pummelled central Gaza by land, sea and air on Wednesday, a day after Israel's Chief of Staff Herzi Halevi told reporters the war would go on "for many months".
Elsewhere, oil loadings at the Russian Black Sea port of Novorossiisk were suspended because of a storm. However, the Caspian Pipeline Consortium (CPC) terminal near the port was open, Kazakhstan's energy ministry said.
