Saudi Arabia says it will respond with "necessary measures" to attacks on two oil facilities as it reiterated the accusation that Iran was behind them.

Axar.az reports citing foreign media.

Minister of State for Foreign Affairs Adel al-Jubeir said the weapons used were Iranian and vowed to release the full findings of the investigation.

Iran denies involvement in the attacks.

Earlier, a senior Iranian military official said Iran was ready to destroy any aggressor after the US announced it was sending troops to Saudi Arabia.

Iranian-backed Houthi rebels in Yemen have said they were responsible for the drone and missile strikes on 14 September that affected the global oil supply.

Tensions between the US and Iran have escalated since US President Donald Trump abandoned a deal limiting Iran's nuclear activities last year and reinstated sanctions.
