I watched the same livestream the AP is screenshotting. There weren't any signs of "shelling". There were two RPG blasts, and then later on tracer rounds fired back towards the source of the RPG blasts. Edit: Saw an explanation that media journalists are probably mistakenly identifying the lighting flares launched in the video as shelling. They're way too slow moving to be shells or explosive rockets.
