The following is a video showing a protester in Egypt standing in front an armored vehicle to halt its advance.

The vehicle, equipped with pressurized water cannon, drove towards a crowd of protesters in order to hose them and push them back.

However, before it reached the crowd, a protester stood in front of it and stopped the vehicle in its tracks.

Several others joined him at the spot in front of the vehicle.

The vehicle then started to advance again and the protester and those who joined him backed down.

Over the last two days, unrest has erupted in Egypt. Protesters have taken to the streets of major cities and are calling for the departure of President Hosni Mubarak.

They've organized much of their activites online through platforms like Facebook.

Also, Egyptians with cameras have recorded photos and video footages of the protests and uploaded them online.
