ODESSA, Ukraine - Sometimes the world of terror and counterterror is amazingly small. The day after at least 43 people were killed and more than 235 injured in a terrorist attack on Istanbul's international airport, Turkish officials announced the arrest of the alleged mastermind behind the attack: Akhmed Chatayev, an ethnic Chechen from Russia who, in the past, had traveled extensively in Ukraine, Austria and Georgia.
