JERUSALEM -- David Barnea, chief of Israel's Mossad intelligence agency, said the organization will continue its activities in Iran, according to a video released by Mossad on Wednesday.

The video shows Barnea addressing operatives at the agency's operational headquarters on Tuesday, just hours after a ceasefire between Israel and Iran took effect.

"We will continue to keep a close eye on all of Iran's projects that we already know in the most in-depth way. We will be there as we have been there until now," he said.

He noted that, "With accurate intelligence, advanced technologies, and unimaginable operational capabilities, we helped the Air Force disrupt the Iranian nuclear program, establish air superiority over Iran, and reduce the missile threat, thereby ensuring the security of the citizens of Israel."

In the video, Barnea also thanked the U.S. Central Intelligence Agency "for the joint activity."

On June 13, Israel launched major airstrikes on different areas in Iran, including nuclear and military sites, killing several senior commanders, nuclear scientists and many civilians. Iran responded by launching several waves of missile and drone attacks on Israel, inflicting casualties and heavy damages.

The ceasefire between the two countries was declared on Tuesday.
