Iraqi warplanes carried out a raid Sunday targeting ISIS commanders in eastern Syria, in the second such strike on the militants since mid-April, Prime Minister Haider al-Abadi’s office said. Abadi ordered the "painful strike" which targeted "a meeting of ISIS commanders south of Al-Dushashiya in Syrian territory", a statement said. F-16 fighter jets were used in the early morning strike and the raid was "successful", the spokesman of Iraqs security media center, General Yehya Rassoul, told Agence France Presse. Dushashiya is in a desert region of Syrias Hasakeh province, where the US-backed Syrian Democratic Forces are fighting the militants. "After receiving information on the target in co-operation with Syrias government and in co-ordination with coalition forces (led by the US), F-16s from the Iraqi air force led strikes against a command post of ISIS, 10 kilometers from the Iraqi border inside Syria," said General Mohammed al-Askari, an adviser to Iraqs defense ministry. "This attack took place following a meeting of several ISIS commanders who were planning terrorist operations on Syrian or Iraqi territory," he said. The target "was completely destroyed and all the officials there were killed," he said, without giving a death toll. Askari also said Iraq hosts a center that co-ordinates military activity with Iran, Russia and Syria "against ISIS". A week ago, Abadi told the media that Iraq would carry out air strikes against ISIS outside the countrys own borders. On April 19, Iraq said it had carried out an air raid against ISIS in Syria that killed 36 militants, near the town of Hajin in the eastern province of Deir Ezzor. Iraq declared victory in December against ISIS, which launched a sweeping offensive in 2014 and at one point controlled a third of the country. The militants still control pockets of desert along the border with Syria.
