Turkish police arrested four Belgians at the border as they tried to enter Syria to fight with the rebels; the four were sent back to Belgium. Last month Belgium had asked Turkey to tighten border security over concerns that a number of Belgians were traveling to Syria to fight; an estimated 100 Belgian citizens are thought to have fought with extremists in Syria. Protests, now relatively subdued, continued against the Erdogan government; some 163 protesters remain in detention in Istanbul.
