Barcelona have cancelled their planned pre-season friendly against Moroccan club Ittihad Riadi Tangier because of the ongoing border crisis involving Ceuta. The crisis escalated after about 78,000 migrants crossed from Morocco into Ceuta by sea last week. Around 100 people died during the crossings, while the influx triggered political tensions among European Union countries that operate under the Schengen border agreement. Most of the migrants have since returned to Morocco, but between 3,000 and 5,000 people are still believed to be in Ceuta. Barcelona will then begin the defence of their La Liga title with a home match against Elche on 23 August.
