Egypt: New Explosion in Sinai?

The Sandmonkey is getting a little bit confused ^[1]. He says that according to News Filbalad ^[2] (an Egyptian news website), the Multinational Force and Observers declared that no explosion took place at Sinai ^[3], and that there are no people injured or killed. That all that happened that a car driven by 2 people- who sustained no injuries- got “destroyed”. On the Other hand, Al Jazeera ^[4] confirms the explosion story and states that it was informed by sources inside the Egyptian National security apparatus.
