The first one I heard, I wasn't listening to and assumed was a door slamming or tire bursting or something; but I've heard hundreds in the last few minutes, some of them deep and booming. There's a shoot-out in the city - and it's nearby; this is Siirt under OHAL, the temporary emergency security measures imposed upon three zones in northern Kurdistan/south-eastern Turkey (Siirt, Şırnak and Hakkari). As someone wryly observed to me earlier today when a police chopper went past, here, 'we live under helicopters'.

Thankfully, the fighting has moved further away and either stopped or moved out of earshot. I'm looking forward to seeing what news reports there are, if any.

As far as I know, it hasn't been reported, so, presumably, at least no-one was injured or killed.
