Sad news. :(
Two things come to mind:
This is to give US/NATO an excuse to come into Pakistan to "secure" vital supplies
Done by proxies to punish NWFP Govt. for its recommendation to halt supplies.
Neither is good.
May the deceased rest in peace.
Way to go. Let us blame US/Nato/Agencies/Angels or any baody under the sun and let us try to cook up more conspiracy theories so that the blame gets deflected from the people doing all this suicide bombing and killing. Let us support the killers.
