Turkey has declared a number of areas near the border with Iraq “temporary security zones” – a sign of increasing activity by the Turkish military in its campaign against Kurdish rebels.
Ankara has denied any major incursion into northern Iraq, however reports suggest a “hot pursuit” led Turkish troops over the border.
The mountainous provinces of Sirnak, Siirt and Hakkari make up the “temporary security zones.”
Turkey has carried out brief raids into Iraq in the past, but the latest incident comes as rebels escalate attacks in their decades-old fight for autonomy in southeast Turkey.
The US government has urged Turkey to be cautious, fearing conflict in northern Iraq, one of the most stable areas in the country.
