While not on the same level as the buses in western Anatolia, bus service into and throughout southeastern Anatolia is decent enough with services from major centres throughout the country. You'll find buses running between most major destinations daily oftentimes more than once daily. In the very deep southeast around Sirnak, Beytussebap and Hakkari, dolmuÅ shared van-taxis and minibuses are far more common but do not run as frequently or on as tight a schedule.
Major airports with domestic services are located in Gaziantep, Urfa, and Diyarbakır in the region.
Diyarbakır and Batman have three times weekly train services Güney Express with Istanbul via the interior of the country, including a stop in Ankara, the national capital. Toros Express which offered some impressive mountainous scenery and connected Gaziantep with Istanbul via Konya and Adana, on the other hand, has been suspended in 2008 and it is not certain when or if it will resume service. However, Gaziantep has a recently introduced weekly passenger train service from the opposite direction, Mosul in northwestern Iraq, crossing a short strip of Syrian territory and running on the rail line just north of no man's land along Turkish-Syrian border. Update, August 2010. Mosul service has been suspended until further notice. Gaziantep also has twice weekly direct train connections with the major Syrian city of Aleppo.
Gaziantep is connected to west by a motorway. There are also other major, but occasionally pot-holed, highways from north, south, and southeast into the region.
