"Cairo factions clash as camels charge through crowds"

This is currently the actual headline of CNN.com, I think it sounds hilarious. Unfortunately, I turned to watch the live stream a little too late to see the camels. What can be seen are protesters, one faction on the left, one on the right, empty space between them, and they are throwing stones at each other. It looks like some kind of mass tennis without rackets.
The caption just read "Activist via Twitter urges women and children to clear the streets". Wow. Again, I highly doubt that a Twitter message reaches the people on the street, especially with the internet down and all. I read that Twitter now offered phonelines to the people in Egypt, where they can leave a spoken message that will then be tweeted out into the world. So this is working the other way round as well? If I send a tweet adressing the people of Egypt, will Twitter call them all by phone and inform them of my tweet?
Apart from that, it was of course a useful security information. Not everyone might realize the danger for children inmidst violent clashes with flying stones, mass brawls, teargas and shots fired and all this.
