DUBAI, June 13 (Reuters) - Two oil tankers were hit in suspected attacks in the Gulf of Oman, shipping firms and industry sources said on Thursday, sending oil prices as much as 4% higher a month after four other tankers were damaged by limpet mines in the region.
One of the tankers, the Front Altair, carrying a cargo of petrochemical feedstock, was ablaze in waters between Gulf Arab states and Iran.
Iran's state news agency said it had sunk, although the Norwegian owner had said it was afloat and its crew were safe. The other tanker was adrift without any crew.

The Bahrain-based U.S. Navy Fifth Fleet said it was assisting the tankers after receiving distress calls. The United Kingdom Maritime Trade Operations, part of Britain's Royal Navy, said it was investigating with its partners.
