Aleppo's Kurdish neighbourhood subjected to rocket and mortar attack

The Syrian Kurdish-majority Sheikh Maqsoud neighbourhood of the Syrian city Aleppo came under rocket and mortar fire on Sunday killing at least nine civilians. 

The area had been under fire for days now. The Syrian Observatory for Human Rights monitor reported, according to Al Jazeera, that more than 70 rockets and mortars were fired at that urban area by various armed groups fighting the Syrian Kurdish People Protection Units (YPG), one of which was the al-Qaeda affiliated Jabhat al-Nusra. 

This comes just after the YPG said on Friday, according to Reuters, that opposition groups in Aleppo were not adhering to the ceasefire agreement and were attacking them. In a statement they said that their opponents "resumed fierce attacks and random bombardment, specifically of Sheikh Maqsoud." 

Many opposition groups accuse the Syrian Kurds of collaborating with the Syrian regime. The YPG made advances in the northwest against hostile armed groups (who had attacked their northwestern canton of Afrin) in that area, including Nusra, as the Syrian military launched an offensive against opposition groups in Aleppo which was backed by Russian airstrikes. 

Turkey responded to this by launching cross-border attacks against the YPG which they ceased following the introduction of the ceasefire over a week ago.
