Turkish security forces have arrested three Uzbek suspects in the killing of a rabbi in the United Arab Emirates. The suspects were apprehended as they left an airport in Istanbul and were immediately extradited to the UAE. The arrest highlights the transnational nature of the attack, although no motive has been offered. Iran has used criminal gangs in the past to target dissidents and enemies, and there are concerns of retaliation against Israel. Diplomatic relations between the UAE and Turkey had been strained, but have improved in recent years.
