April 9 (UPI) -- The Strait of Hormuz is not open to traffic despite this week's cease-fire between the United States and Iran, the head of the United Arab Emirates' state-owned oil company said Thursday.

Sultan Ahmed Al Jaber, CEO of Abu Dhabi National Oil Company, called on Iran to "unconditionally" open the strait with "no strings attached."

"This moment requires clarity," he said in a post on LinkedIn. "So let's be clear: The Strait of Hormuz is not open. Access is being restricted, conditioned and controlled."

Iran faced a Tuesday evening deadline to reopen the Strait of Hormuz to the United States and its allies. Tehran had effectively closed the waterway to most traffic after the United States and Israel launched attacks on Iran starting Feb. 28.
