Turkish officials are keeping a brave face, yet the problem is big and growing as the presence of 1.5 million Syrian refugees are becoming an explosive issue in Turkish society.The official line is that Turkey, just like the people of Medina who embraced Prophet Muhammad and his followers who were forced to emigrate from Mecca in view of the hostile actions of the unbelievers, has embraced the Syrians fleeing the civil war in their country. The often-heard explanation from Turkish officials is the words of the prophet, "We cannot rest in peace when our neighbor is suffering."On Tuesday news came out that a Syrian killed his landlord in the southeastern city of Gaziantep who was trying to evict him from his house. The incident sparked an angry outcry in the city, and on Tuesday night several locals attacked Syrians living in the city. Cars with Syrian license plates were attacked, and one car was set afire. Some Syrians were stabbed and were taken to hospital.Several months ago when there were incidents in the Ankara neighborhood of Altındağ we had warned that this was the tip of the iceberg and that the situation was gradually turning into a very serious menace ready to explode.Of course the Syrians are welcome and no Turk will be able to rest in peace as long as there is such gross suffering in Syria or in Gaza or in Iraq. Turks are already preparing to set up refugee camps to host hundreds of Yezidis fleeing the Sunnis extremists in Iraq. But then the people should also respect the Turkish hospitality accorded to them and should not abuse their presence here.We see that while many Syrians are showing respect and regard to Turkish sensitivities, there are some who are acting in a very hostile manner. They are clearly abusing the hospitality accorded to them, and there is growing social resentment that is creating some serious explosive situations like the incidents in Gaziantep.There are tens of thousands of Syrian beggars in the streets. The Interior Ministry has already moved to put an end to this, but we see that they are facing an uphill struggle.Syrians are spread all over the country, and there are no serious official records about them, which is an invitation to serious trouble in the future. All Syrians should be registered and carefully monitored. They are guests, and when their country returns to normal then they will go back to Syria, and they should know that their presence here is not permanent. What is sad is that it seems this will not happen any time soon. That too is complicating the situation as the longer the Syrian crisis continues the longer these people stay and the more explosive the situation becomes.Beyond this there is an inclination among some Syrians to resort to criminal means and that too should be halted or else this will only fuel existing Turkish public resentment.Syrians have to be given clear messages that even though their extended stay is welcome in view of the Turkish traditions to host neighbors in trouble and the teachings of our religion, this should not be abused. Turks are sensitive, tolerant and patient. But this should not be tested.
