Australia uncovers al Qaeda links to Bali blasts

Again, what do we mean by links? From everything I read, al-Qaeda has ties to terrorist groups all over the world, including Western, nominally Christian groups like the IRA and ETA. Jemaah Islamiah, the Indonesian group many suspect of the attack, is said to be linked to al-Q. But that doesn't mean that Osama's boys planned the Bali attack or even necessarily knew about it.
