Iran has received its first revenue from tolls imposed on ships transiting the Strait of Hormuz during the U.S. and Israel war on the country, a senior official in Tehran announced Thursday.

"The first revenue received from the Strait of Hormuz tolls was deposited into the Central Bank account," said deputy speaker of parliament, Hamidreza Hajibabaei, according to Tasnim news agency.

Other Iranian media carried the same statement, without elaborating.

The Strait of Hormuz, a key energy chokepoint, has become a major flashpoint since the outbreak of the Middle East war on Feb. 28.

Iran has allowed only a trickle of ships to pass through the waterway, a route that in peacetime accounts for a fifth of the world's oil and gas flows, along with other vital commodities.
