A video of Thursday's operation showed two F-16 fighter jets destroying a house in eastern Syria.

"The Iraqi air raids, carried out by several F-16s in Syria on April 19, targeted IS terrorists who represented a danger to Iraq," said General Yahya Rasool, spokesman for the Joint Operations Command (JOC), which coordinates the fight against IS in Iraq.

"According to our information, the raids took place while there was a meeting of terrorist leaders and it achieved its goal with the death of 36 of them," he said.

The US-led coalition battling IS jihadists confirmed the raid, which took place near the town of Hajin in the eastern Syrian province of Deir Ezzor, about 50 kilometres (30 miles) from the Iraqi border.

"These raids prove Iraq's commitment to destroy the remnants of IS that continue to threaten citizens," Prime Minister Haider al-Abadi's office said on Thursday, adding that the operation was planned and executed by JOC, with support from the coalition.
