"We're going to continue our scanning so we will see what we can do ... to figure out what we can find out beneath it, or just by the end of this corridor," he told reporters after a press conference in front of the pyramid.
Five rooms atop the king's burial chamber in another part of the pyramid are also thought to have been built to redistribute the weight of the massive structure. It was possible the pharaoh had more than one burial chamber, Waziri added.
Scientists confirmed the presence of the corridor using radar and ultrasound, before retrieving images of it by feeding a 6mm-thick endoscope from Japan through a tiny joint in the pyramid's stones.
In 2017, Scan Pyramids researchers announced the discovery of a void at least 30 metres long inside the Great Pyramid, the first major inner structure found since the 19th century.
