Saudi Arabia has suspended a key oil pipeline after it was attacked by drones from Iraq.
Addressing the claims, Baghdad said it had a fired military commander and launched an investigation after admitting that the drone attack on Saudi's East-West pipeline had originated in one of its provinces bordering Iran.
The 1,200 km (745 mile) pipeline has helped Saudi Arabia, the world's largest crude oil exporter, bypass the Strait of Hormuz.
Saudi Arabia's oil pipeline attacked as Houthis seize back key island
The drone attack and operation suspension came amid a major win for the Iranian-backed Houthi rebels in Yemen, who seized he strategic island of Mayun located inside the Bab el-Mandeb Strait at the southern entrance of the Red Sea.
The developments have squeezed both sides of the Arabian Peninsula, pushing crude oil prices to over $100 a barrel for the first time since July.
As per Houthis, navigation through the Bab al-Mandab Strait was "safe for all but Saudi Arabia after the latest advances.
Riyadh on Friday said it had shut the pipeline as a precaution, as satellite images of scorched ground and smoke near the site emerged.
Following the attack, the foreign ministry said the attack resulted in some injuries and damage, which was still being assessed.
The pipeline has been moving 4% to 5% of the global oil supply, news agency Reuters has reported, citing ship tracking companies and analysts.
Will Saudi Arabia retaliate after the drone attack?
Saudi Arabia has chosen not to retaliate at this stage, its foreign ministry says, following a call from Iraq's prime minister.
It said the kingdom would "support the efforts of the Iraqi government" to "prevent attacks" launched from the country against neighbouring states.
"The Kingdom of Saudi Arabia affirms that it reserves its right to take all necessary measures to safeguard its sovereignty and security, protect its facilities, and ensure the safety of its citizens and residents," the statement added.
The Gulf Co-operation Council, made up of representatives from the United Arab Emirates, Bahrain, Oman, Qatar and Kuwait, also issued a statement condemning the attack.
"This attack represents a dangerous escalation and an unacceptable threat to the security of the Kingdom of Saudi Arabia, its territorial integrity, and its vital installations, as well as a flagrant violation of the principles of international law," secretary general Jasem Mohamed Albudaiwi.
