TEHRAN (FNA)- Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei praised the Islamic Revolution Guards Corps (IRGC) Navy for its swift reaction to US naval forces' trespassing on Iran's territorial waters last week.

"They displayed Iran's identity and power against the enemy aggression," Ayatollah Khamenei said, addressing the Iranian officials responsible for the February parliamentary elections, in Tehran on Wednesday.

He appreciated the IRGC Navy for defending the country's territorial waters, and said, "The Iranian officials should also show similar actions in all other fields and show powerful reaction wherever the enemy violates Iran's national interests."

The IRGC seized two US Navy boats on January 12 and detained ten US marines on Iran's Farsi Island in the Persian Gulf. Nine men and one woman arrived in Iran's territorial waters in the Persian Gulf illegally when they were captured by the IRGC Navy.

Each of the two US Navy boats that were 3 nautical miles deep into the Iranian waters when they were captured by the IRGC Navy's second naval zone were equipped with three 50mm caliber machine guns and other light and semi-heavy weapons.

IRGC officials said the coordinates recorded on the GPS devices taken from the 10 US marines confirmed their trespassing as well.

The 10 US marines were released by the IRGC a day later. The IRGC declared in a statement that "it has released the US marines and their vessels in international waters" after its investigations showed that they had gone astray during their voyage in the Persian Gulf.

In its statement, the IRGC pointed out that its investigations show that the US combat vessels' illegal entry into the Iranian waters was not the result of a purposeful act.

"Following technical and operational investigations and in interaction with relevant political and national security bodies of the country and after it became clear that the US combat vessels' illegal entry into the Islamic Republic of Iran's waters was the result of an unintentional action and a mistake and after they extended an apology, the decision was made to release them," the statement said.

"The Americans have undertaken not to repeat such mistakes," it added, and continued, "The captured marines were released in international waters under the supervision of the IRGC Navy moments ago."

The IRGC statement blamed the US flotilla for its "excited and unprofessional moves", but said the IRGC navy could handle the situation and restored calm to the region through powerful and wise moves.

Senior US officials, including Secretary of State John Kerry, were in contact with their Iranian counterparts on the fate of the marines since their detention day, and according to Iranian officials, Foreign Minister Mohammad Javad Zarif had told Kerry that the US should extend a formal apology first.

According to the statement, the Americans have extended an apology.
