ISIS Sustains Heavy Casualties Amid Syrian Army Counter-Assault at Deir Ezzor May 29, 2015 War Reports 1557 Source: The Arab Source The Syrian Arab Army’s 104th Airborne Brigade of the Republican Guard – in coordination with the 137th Artillery Brigade of the 17th Reserve Division – launched a counter-assault against the militants from the Islamic State of Iraq and Al-Sham (ISIS) after the latter stormed the eastern barricades of the Deir Ezzor Military Airport on Friday morning. Following the failed infiltration attempt by ISIS, the SAA’s 104th and 137th Brigades carried out a powerful assault on the enemy combatants at the Siasiyeh Bridge and the Al-Haweeqa Quarter of Deir Ezzor City, killing 33 militants before they were able to seize control of the ISIS command-and-control center and their large cache of weapons stored inside of the building. The Syrian Armed Forces did not stop there, they followed-up their success at Al-Haweeqa and the Siasiyeh Bridge with another assault at the eastern farms of Al-Muri’iyah, where they were able to take full control of the corn farms after engaging a large contingent from ISIS inside of this village near the Deir Ezzor Military Airport. At Al-Jarfa – on the other side of the Deir Ezzor Military Airport – the Syrian Armed Forces added to their buffer-zone after pushing back the swarming ISIS combatants to the eastern flank of the village; this was followed by a series of airstrikes from the Syrian Arab Air Force (SAAF), who relentlessly bombarded the terrorist group over a dozen times on Friday. The firefights did not stop there: the Syrian Armed Forces and the militants from ISIS exchanged gunfire at a number of areas inside the provincial capital of Deir Ezzor on Friday; this was the bloodiest day for ISIS in quite a while, as the terrorist organization lost over 80 militants during these firefights. According to a military source inside the provincial capital of Deir Ezzor, ISIS and the Syrian Armed Forces also clashed at the Al-‘Arfa, Al-Hamidiyah, Al-Kanamat, Al-Jubeileh, and the Al-Rashidiyah Quarters inside the city.
