The Saudi-led coalition fighting in Yemen said it had thwarted an attack on a Saudi oil tanker over the weekend by Houthi fighters near the Red Sea port of Hodeidah.
The Red Sea is a key shipping route for world trade that connects the Middle East to Europe via the Suez Canal.
The report presented to the UN Security Council on 9 January said: 'The panel has identified missile remnants, related military equipment and military unmanned aerial vehicles (UAVs) that are of Iranian origin and were introduced into Yemen after the imposition of the targeted arms embargo'.
While SABA gave no details on how Houthis could carry out any such move, the Bab al-Mandab strait, where the Red Sea meets the Gulf of Aden in the Arabian Sea, is only 20 km (12 mile) wide, making hundreds of ships potentially an easy target.
Addressing supporters in the southern Shabwa province - where he had travelled to offer condolences to the family of Aref al-Zouka, who was killed along with Saleh in the attack on Saleh's residence in Sanaa - Tareq said he remained committed to his uncle's quest for peace in Yemen.
Saudi-led coalition air strikes on a marketplace and house in northern Yemen have left at least 14 people dead, witnesses and said Thursday.
According to excerpts obtained Friday by The Associated Press and diplomats, the 79-page report paints a devastating picture of the Arab world's poorest nation caught in a conflict that many view as a proxy war between regional rivals Saudi Arabia and Iran.
In November, the coalition tightened the blockade after the Huthis fired a missile into Saudi Arabia that was intercepted near Riyadh's worldwide airport.
The war has killed more than 10,000 Yemenis, mostly civilians, and pushed the country to the brink of mass starvation.
