Don’t watch this if you have a weak stomach. Even if you have a strong stomach it is hard to watch.
Here is a report from Coptic Solidarity (which has a shorter version of the video).

For the second time in as many days, Egyptian armed force stormed the 5th century old St. Bishoy monastery in Wadi el-Natroun, 110 kilometers from Cairo. Live ammunition was fired, wounding two monks and six Coptic monastery workers. Several sources confirmed the army’s use of RPG ammunition. Four people have been arrested including three monks and a Coptic lawyer who was at the monastery investigating yesterday’s army attack.
Monk Aksios Ava Bishoy told activist Nader Shoukry of Freecopts the armed forces stormed the main entrance gate to the monastery in the morning using five tanks, armored vehicles and a bulldozer to demolish the fence built by the monastery last month to protect themselves and the monastery from the lawlessness which prevailed in Egypt during the January 25 Uprising.

Asia News says:

The confrontation was sparked by the construction of fences around the convents to protect them from marauding criminals who escaped prison in the wake of the 25 January uprising. After issuing a 48-hour demolition order, the army moved in. Some 7,000 Copts protest in Tahrir Square.

There are more details at how the “situation” arose at the Asia News link.
This seems to be a rather excessive reaction to what amounts to a building code violation.
And don’t forget: always take your camera to the action. Evidence is always good to counter the “narrative”.
Here are a few pages of books on the Copts and Egypt.
