On June 13, 2019 (May 11, 2019 in the lunar calendar), oil tankers were attacked in the Gulf of Oman. On June 13, 2019, two oil tankers belonging to Norwegian and Japanese companies were attacked in the waters of the Gulf of Oman and exploded, causing a fire on board. On the 14th, Iran sent experts to the area where the incident occurred. The Iranian side said that the fire of the two oil tankers has been brought under control. The United States accused Iran of this attack, and Iran's rebuttal of the US accusation is groundless. The truth about this incident is mysterious. At present, there are reports that the oil tanker was attacked by underwater weapons, and there are also claims that the damage to the oil tanker was an adsorption explosive device or a UFO. Iranian media broadcast footage showing Iranian rescue vessels involved in the rescue and the safe transfer of 44 crew members on two tankers to the Iranian port of Jasq. The US side said that US intelligence showed that Iran carried out the attack. The US Central Command also released images of what it said was Iranian Islamic Revolutionary Guard personnel removing unexploded devices from the attacked tanker. Iranian Foreign Minister Javad Zarif said that the attack on the tanker was quite suspicious. The US accusation was one of the sabotage plans of the United States and its allies hostile to Iranian forces. It was a clumsy means for the United States to put maximum pressure on Iran, and it was also a traditional sabotage diplomatic trick used by the United States. In response to the alleged attack on two oil tankers in the Gulf of Oman, UN Secretary-General Guterres on the 14th once again condemned the incident in an interview with the media and said that the truth must be found out about the incident. On the 14th, the Russian Foreign Ministry urged all parties not to draw hasty conclusions until the results of a fair investigation are available. Russia said that all relevant parties in the Gulf region should exercise restraint over the incident. Russian Deputy Foreign Minister Ryabkov warned on the same day that relevant parties should not attempt to blame Iran for the incident and use it to exacerbate the situation in the region.
