Some began to label Qatar a terrorist haven in part because it is harboring Hamas leader Meshaal . They also harbor Husam Badran , former leader of Hamas 's military wing in the northern West Bank . Husam Badran , current media spokesman for Hamas , was the instigator of several of the deadliest suicide bombings of the second intifada , including the Dolphinarium discotheque bombing in Tel Aviv , which killed 21 people . Turkey has also been criticized for housing terrorists including Saleh al-Arouri , the senior Hamas officer , known for his ability to mastermind attacks from abroad . Al-Arouri is alleged to have orchestrated the June 2014 abduction and killing of three Israeli teenagers and to have started the 50-day war between Israel and Palestine , and now lives in Turkey
