Original sentence: At the same time, two anonymous FSA leaders, and a secular rebel in north Syria, expressed disapproval of the Islamist ‘religious prison’ Nusra might be wanting to turn Syria into.During successful Syrian opposition offensives in the northern Idlib Governorate from March until May 2015 (see also March–April offensive and April–June 2015 offensive), al-Nusra effectively coordinated its operations with Free Syrian Army, moderate and conservative Syrian Islamists, and some independent jihadist factions.In 2015, rebel factions in southern Syria vowed to distance themselves from the ‘extremists’ of al-Nusra in April 2015, but were seen cooperating with them in Daraa only days later.In October–December 2012, and especially after it's terrorist designation by the US, Nusra received words of praise and appreciation their efforts in the “revolution” against Assad from non-specified ‘rebels’, a Free Syrian Army (FSA) spokesman in the Aleppo region, a group of 29 civilian and military groups, and the leader of the Syrian National Coalition
Edited sentence: At the same time however, two anonymous FSA leaders, and a secular rebel in north Syria, expressed disapproval of the Islamist ‘religious prison’ Nusra might be wanting to turn Syria into.During successful Syrian opposition offensives in the northern Idlib Governorate from the second half of March until early May 2015 (see also March–April offensive and April–June 2015 offensive), al-Nusra effectively coordinated its operations with Free Syrian Army, moderate and conservative Syrian Islamists, and some independent jihadist factions.In 2015, pronouncements of other Syrian rebel groups about their opinions of al-Nusra seemed sometimes unreliable: factions in southern Syria that in April 2015 had vowed to distance themselves from the ‘extremists’ of al-Nusra were seen cooperating with them in Daraa only days later.In October–December 2012, and especially after on 10 December the US had designated Nusra as a foreign terrorist organization, non-specified ‘rebels’, but also a Free Syrian Army (FSA) spokesman in the Aleppo region, and a list of 29 civilian and military groups,  and the leader of the Syrian National Coalition, expressed praise and appreciation for al-Nusra’s efforts in their communal “revolution” against “the regime” of Assad
