Qatar versus Lebanon: fears of the Qatari royal family

Tomorrow, Lebanon's national soccer team will face Qatar's national soccer team in Beirut.  But there will be no spectators: Lebanese governments banned them.  Why? Apparently, the Qatari government knew that the Lebanese spectators will chant against the Qatari royal family and it threatened to expel all Lebanese from Qatar if such chants were allowed.  The Lebanese government acted accordingly.
