Very. Listening to the news now. Traces of explosives found.
Scotland Yard had knowledge of threats of terrorists attacks and warned the Israelies.
Al Quaida or group affliated with them.
Similiar to IRA bombings.
Hope no one decides to think it's the IRA.
I think Al Qaida could have got IRA help - after all the IRA are the experts when it comes to terrorist attacks on London.
