ISTANBUL (AP) - Turkey's deputy prime minister says a Turkish jet has shot down a Syrian military helicopter after it entered Turkish airspace.
Bulent Arinc told reporters in Ankara that the pilots of the helicopter were warned repeatedly on Monday after they had strayed 2 kilometers (more than 1 mile) into Turkish airspace.
