Soldiers in the compound reported hearing a sudden burst of gunfire and then silence.

I was jotting that in my notebook when the first burst of gunfire rang out.

Another burst of gunfire broke out three hours later as forces swept the area to make sure it was clear.

Another squeezed through the rear door of the coach, only to tumble out backwards after a burst of gunfire from within.

Then there was a powerful burst of gunfire.
