Israeli raid 'hits Gaza vehicle'

How does the BBC know any of the details in their report?

"Three suspected militants have been injured in an Israeli air strike on a vehicle in Gaza, witnesses say."

Would that be Hamas then? Then the BBC just throw this out without attributing it to anyone. "At least two civilians were also hurt in the attack."

But the BBC report that Israel is not the source of their reporting.

"The Israeli military said it had carried out a raid but gave no details, saying it was part of operations against "terrorist activity".

So, who is the BBC's source for their claims? Hamas?
