On 12 March, pro-opposition sources claimed the rebels cut the M-5 highway at Khan Shaykhun; 13 days later it was reported that the rebels seized 15 Syrian Army checkpoints in Khan Shaykhun after days of fighting. According to Col. Afif al-Suleimani, head of Idlib's rebel Military Council, the Army withdrew many of its soldiers from Idlib province to reinforce their forces in Latakia province after the 2014 rebel offensive at Latakia was launched against the coastal area. The rebels then advanced towards Khan Shaykhun resulted in both the lifting of the siege of the town and cutting the supply line to Syrian Army bases further north in the province. Also, on 29 March, they reportedly captured parts of the Shiite town of Al-Fu'ah, northeast of Idlib city. On 4 April, four rebels were reportedly killed by clashes around Sehyan checkpoint north of Khan Shaykhun. It was also reported that Baboulin town and al-Salhiya village were captured by the rebels, thus cutting off the supply route and highway to the Wadi Deif and Hamidiyah army bases at Maaret al-Numan. At least 18 regular soldiers were reportedly killed in the clashes and two tanks were disabled. After Baboulin was captured, clashes took place along a nearby 20-mile stretch of highway between Morek and Maaret al-Numan. A day later, the SOHR reported that the rebels seized a checkpoint at Khan Shaykhoun over night. On 8 April, rebels detonated two suicide cars at the Khazanat fueling base east of Khan Shaykhun, followed by clashes and three days later reportedly took an Army checkpoint at the crossroads of the Heish, but Syrian Army units took it back the next day. Despite this setback, the rebels captured the al-Sayyad checkpoint the same day after heavy clashes with Army units in the southeast of Khan Shaykhoun according to the SOHR. On 15 April, 21 rebels and a number of Army soldiers were reportedly killed in clashes around Qmenas town. In addition, 6 rebels were killed while no less than 40 were injured, and the connection was lost with 25 rebels after an ambush by Syrian Army units around Al-Hamedya camp It was also reported that the FSA affiliated Hazzm Movement had received 20 TOW anti-tank missiles from a "Western source". On 5 May, rebels detonated a 'tunnel bomb' under the al-Sahabh checkpoint in the east of Khan Shaykhoun and captured it. According to the SOHR, about 30 pro-government fighters were killed in the blast. Pro-government sources denied this claim and only reported several wounded. On 14 May, the Wadi al-Deif base was struck by another 'tunnel bomb'. According to the SOHR, tens of pro-government fighters were killed and wounded by the explosion. On 24 May, according to the SOHR, rebels launched an offensive towards Hish and reportedly captured the Kafr Bassin and Hish intersection Army checkpoints. The next day, six car bombs were detonated by the rebels: Four at checkpoints in the Al Arba’in Mountain area and two at the Khazanat Army base east of Khan Shaykhoun. According to the SOHR, tens of pro-government fighters were killed and injured by the blasts in the Al Arba’in Mountain area and at least 16 in the Khazanat base. The attacks resulted in rebel advances in the Al Arba’in Mountain area and the capture of the Khazanat base. Pro-government sources denied all of this and claimed that the army was advancing in the Al Arba’in area. The following day, rebels captured the al-Salam checkpoint west of Khan Shaykhoun, thus completely securing Khan Shaykhoun and its surroundings, and a checkpoint in the Hish area.
