RTF and interceptions are Usual business. They just get more systematic since 9.11. No big deal nowadays and since nothing serious hapens afterwards, the problem continues.
To my US colleagues : transposing that same situation in the USA : let's say a 737 coming from Mexico dest Canada in RTF for 700 miles after the Mex border . Would it be just intercepted and escorted to the border or forced to land in a USAF base somewhere in between ?
That could perhaps explain why there are apparently far fewer long unitentional RTF in the US than in Europe.
