Al Jazeera was reporting Friday that its Cairo bureau had been ransacked and equipment destroyed by "gangs of thugs."
The news net posted a brief story about the attack on its Web site, and various news operations were reporting it at press time.
There were also reports that its Web site had been hacked.
The Egyptian government earlier in the week revoked its license to broadcast in the country and was shutting down the bureau.
It has remained a news link to the crisis nonetheless, including by an online stream of live coverage of the protests, now in their 10th day.
