A Chemical Attack on Beirut’s Airport?

This news item (english) just doesn’t make sense. Why would a Pakistani national want to commit such a horrible act of terrorism in Beirut’s RHI Airport?

Lebanon doesn’t have a significant bilateral relationship with Pakistan. We don’t typically disagree on foreign policy. The Lebanese do not employ pakistanis as domestic workers. The only explanation I can think of is an Alqaeda style act of terrorism for the sake of terrorism.

Now why would a newspaper close to Hezbollah post such a thinly sourced scare-mongering piece about an upcoming Alqaeda attack? I’m sure it’s a coincidence that there’s an effort in the country to smear the Sunnis as Alqaeda hosts and sympathizers.
