Earlier this month, two Saudi oil tankers and two other vessels were targeted by acts of sabotage in the United Arab Emirates' (UAE) exclusive economic zone. US officials told media that Iran was responsible for the blasts without providing any evidence and despite the fact that both Saudi Arabia and the UAE haven't accused Tehran of the incident, ONAreports citing Sputnik.
According to Bolton, the tankers which witnessed explosions two weeks ago off the coast of Fujairah, UAE were damaged by "naval mines almost certainly from Iran".
Previously, US Secretary of State Mike Pompeo brought the same charges, claiming that Tehran might be behind the incident. The Islamic Republic, however, repeatedly denied the allegations, stressing that the attacks must be investigated in order to preserve stability in the region.
The news comes as Washington has stepped up the US military presence near Iran's borders, deploying an aircraft carrier strike group, Patriot missiles, B-52 bombers and F-15 fighters to the Middle East.
Addressing the move, Bolton has called it a "clear and unmistakable message" to Tehran amid the partial suspension of the nuclear deal by Iranian authorities.
