Iran vowed on Saturday not to let an attack on one of its oil tankers off the coast of Saudi Arabia to go unanswered, the semi-official ISNA news agency reported.
Ali Shamkhani, secretary of the Supreme National Security Council, said clues had been uncovered as to who was behind what he called a “missile attack” on the Sabiti tanker.
“Maritime piracy and wickedness in international waterways… will not be left unanswered,” he said, quoted by ISNA.
“By reviewing the available video and gathered intelligence evidence, the primary clues to the dangerous adventure of attacking the Iranian oil tanker in the Red Sea have been uncovered,” he added.
Shamkhani warned of “disturbing risks” for the global economy as a result of insecurity in international waterways.
The National Iranian Tanker Company, which owns the Sabiti, said its hull was hit by two separate explosions on Friday off the Saudi port of Jeddah,
But the state-owned company denied reports the attack had originated from Saudi soil.
