Turkey condemns attacks on oil tankers in Gulf of Oman
"We are concerned that commercial ships in the Gulf region have been targeted for second time in the last one month," the Turkish Foreign Ministry said in a statement.
The two tankers, the Marshal Islands-flagged and the Panama-flagged, were on their ways to Taiwan and Singapore from Qatar and Saudi Arabia, respectively.
The tanker is operated by Tokyo-based Kokuka Sangyo Co., according to Kyodo.
Iran's Foreign Minister Javad Zarif has said the attacks were "suspicious" for having been perpetrated during talks between Japanese premier Shinzo Abe with the country's Supreme leader Ali Khamenei.
Late last month, the UAE said four vessels, including two oil tankers, were hit by sabotage attacks near its territorial waters, without blaming anyone for the attacks.
Riyadh blamed Iran-backed Houthi rebels in Yemen for the attacks.
