ANKARA, March 30: Turkey was expected to allow the United States to use a key military base in the south of the country as a logistical cargo hub for operations in Iraq and Afghanistan, a Turkish official said on Wednesday. Turkish officials have completed technical work on a plan allowing US planes to use the Incirlik base in Adana province, the official said. Ankara and Washington have been negotiating about the base for the past several months amid tensions stemming from differences over the invasion of Iraq.—AFP
