ERBIL, Kurdistan Region —Syrian rebel fighters seized the al-Tanf border crossing with Iraq from the Islamic State (ISIS) late Friday, which is considered one of the extremist group’s major centers in Syria. According to the Syrian observatory for human rights the rebels who attacked ISIS had crossed from Jordan for the assault. Al-Tanf also known as Tadmur is considered ISIS's biggest concentration in central Syria and it is only 240 km (150 miles) from Palmyra. The extremist group captured the crossing last May, connecting its some of its Syria territories to Iraq. Major hostilities in Syria came to an end late last month as part of the ceasefire but ISIS and the al-Nusra Front are still being targeted by all sides as they are excluded from the truce
