A billboard displayed in Tehran broadcast a video of US and Israeli ships being destroyed just days before an attack took place on Gulf tankers.
It showed destroyed American and Israeli ships in a sea of what appeared to be made up of Palestinian scarfs (keffiyehs) with the caption 'We Drowned Them All', in Farsi, Hebrew and English.
The board had been displayed outside in Vali-s Asr Square in Tehran's commercial centre on Wednesday 29 May, in honour of Quds Day, an event held to celebrate the last day of Ramadan.
The day had been initiated by the Islamic Republic of Iran in 1979 to express support for the Palestinians and oppose Zionism and Israel.

Oil tankers were attacked on Thursday near the strategic Strait of Hormuz in the Persian Gulf. The suspected attacks occurred about 25 miles off the southern coast of Iran.
Two tankers were attacked, one was left ablaze with both being left adrift. The US navy's fifth fleet said it had been assisting the tankers which issued distress calls – the crew from both tankers were evacuated.
Iran denied any role in Thursday's apparent attacks, which have again rocked the Persian Gulf amid heightened tensions between Tehran and Washington over the unravelling nuclear deal with world powers.
Four other oil tankers off the nearby Emirati port city of Fujairah suffered similar attacks in recent weeks, and Iranian-allied rebels from Yemen have struck US ally Saudi Arabia with drones and missiles.

The US Navy sent the USS Bainbridge, which picked up 21 sailors from the Kokuka Courageous, and they stayed overnight on the destroyer,
