If Nobody Claims Responsibility, Is It Still Terror?

Is there a reluctance to call yesterday’s bulldozer rampage “terror” because it was carried out by a lone individual? AP seems to suggest just that:

Like the perpetrator of the previous attack, the driver in Tuesday’s incident was a Palestinian from east Jerusalem with an Israeli residence permit and he drove the same type of front loader, police said. Israeli police called it a “terror attack” but no group immediately claimed responsibility.

“Terror” can be spontaneous, and a “terrorist” doesn’t necessarily have to have the backing of any organization.

UPDATE 12:20 pm: The BBC makes the same ridiculous assertion:

Israeli police called it a “terror attack”, although there was no immediate claim of responsibility by any Palestinian militant organisation.

UPDATE 1:50 pm: As does the Daily Telegraph:

Israeli officials described the attack as terrorism although there was no immediate evidence that the attacker was working for any Palestinian militant group.
