US Sponsored Terrorism in Iran?

I think people should be very concerned about the following:

"A car loaded with explosives blew up near a bus carrying members of Iran's elite Revolutionary Guards in southeastern Iran, killing 18 of them, the state-run news agency reported today.

The car stopped in front of the bus near Zahedan, the capital of Sistan-Baluchestan Province, the official Islamic Republic News Agency reported. It called the attack a terrorist operation and said the car's occupants fled on motorbikes seconds before the car exploded.

"This blind terrorist operation led to the martyrdom of 18 citizens of Zahedan," IRNA quoted a Guards commander, Qasem Rezaei, as saying.

State-run television said the bus had been taking them to work when the attack took place. There was no immediate claim of responsibility but Rezaei blamed "insurgents and elements of insecurity" for the attack. Hossein Ali Shahriyari, a deputy representing Zahedan, told an open session of the parliament today that "insurgents and drug traffickers" were behind the attack.

Shahriyari called lawless regions in southwestern Pakistan a safe haven for Iranian insurgents and drug traffickers, and called on the government to take up the issue with Islamabad."
