The Syrian government claiming that this is the result of terrorist action is a laughable lie. Here's why. First, look at a quick overview of what's coming out of Syria now:
The rebels finally acquired ground-to-air rockets and have shot down at least one government helicopter. This is a pretty huge step since it means they can finally do something about the government forces' air superiority. http://atwar.blogs.nytimes.com/2012/11/ ... r-missile/
Of course, now the government will just shell harder. Probably with cluster bombs:http://rogueadventurer.com/2012/11/27/u ... munitions/
And the Syrian government is apparently also using white phosphorus against the rebels, which is pretty much the shittiest possible way to bombard ground forces. (I mean, if you're at war, just blow them up, don't light them on fire. I know it's all a matter of degree, but damn.) Here's some footage of that:http://yallasouriya.wordpress.com/2012/ ... mbs-syria/
This is the 21st century, and anything that happens anywhere can be on the internet within minutes. The Syrian government knows that if they can control information, they control how the rebels are perceived by the world-- currently it's pretty forking obvious that Assad is a massive bully trying desperately to retain control over his dictatorship using the worst measures possible, and they keep escalating-- WP is banned by every other country, pretty much, even for use against enemy combatants, let alone against civilians.
The rebels use the infrastructure for coordination and for getting information out to the world. Assad's government knows this. In the past couple of months the rebels have had some pretty major victories and have captured a bunch of weapons and stuff and are now able to more effectively and successfully fight back:http://www.bbc.co.uk/news/world-middle-east-20493687
Assad knows that if this continues he will lose, and apparently destroying his own infrastructure is worth the sacrifice in order to cripple the rebels' ability to communicate both internally and externally.
The rebels wouldn't go after the information infrastructure-- they use it too heavily. This is a desperate act by a failed government.
