A curious attack

Revolutionary Guards die in Iran border bus blast

Eleven Iranian Revolutionary Guards were killed yesterday when a bomb destroyed their bus in a volatile border area of Iran.
A semi-official Iranian news agency said the daylight attack in Zahedan, the capital of Sistan-Baluchistan province, had been claimed by Jundallah (Allah’s Brigade), an extremist Sunni rebel group that Iranian officials have previously linked to al-Qaeda.

So if al-Qaeda targeted Iranian troops, shouldn't we help Iran? Isn't it my enemy's enemy is my friend?

Or is this fitting into some big plan? Iranian troops attacked, they venture into Iraq to capture the perpetrators, they run into U.S. troops - justification for an Iranian invasion.

Wonder who created the bombs used by Jundallah? Let's hope Iran doesn't have proof that we made it . They wouldn't steal W's propaganda idea would they?
