DUBAI, United Arab Emirates (AP) — Two tankers were struck by projectiles Tuesday in the Strait of Hormuz, the British military said, in the latest attacks targeting vessels moving through the narrow mouth of the Persian Gulf.

One of the tankers was traveling off the coast of Oman and caught fire, according to the United Kingdom Maritime Trade Operations center. Iranian state television said the liquefied natural gas tanker came under attack after ignoring warnings but did not directly claim the assault.

It was not immediately clear where the second tanker was when it was hit. The vessel was believed to have sustained structural damage, but no one was injured, the maritime agency said.

Tehran, which has repeatedly declared that only its approved route through the strait is safe, is suspected of attacking other ships that have used another route close to the Omani shore.
