Turkey asked US formally on Tuesday to avoid another violation of its airspace after an incident that exposed tensions between the NATO allies.
Last week, two US F-16 warplanes briefly infringed Turkish airspace near the Iraqi border. US diplomats say the incident was an "accident". Turkish media say it was intended to send a message to Ankara not to send its troops into northern Iraq.
"After we received detailed technical information from the General Staff on the incident, the necessary diplomatic initiative was made today in the presence of (a representative of) the US embassy," the Foreign Ministry said in a statement.
A Turkish Foreign Ministry official said "In the note given (to the embassy representative) it was requested that this kind of incident not be repeated."
The incident has coincided with increased media speculation in Turkey, which faces a national election in July, of a possible Turkish military incursion into northern Iraq to crush Turkish Kurdish rebels hiding there.
The rebels use northern Iraq as a springboard to attack military and security targets inside Turkey. Ankara has long urged US and Iraqi forces to crack down on the rebels.
Foreign Minister Abdullah Gul said on Friday there were no preparations in parliament to give approval to send troops into Iraq. In its statement on Tuesday, the Foreign Ministry said it was working closely with the General Staff on the issue.
Turkish newspapers have suggested the two institutions have not been coordinating their actions. The General Staff recently helped prevent Gul being elected president in an election in parliament that has now been postponed.
