Turkish President Recep Tayyip Erdogan and other Turkish officials announced the new location of the tomb, around 200 metres away from the Turkish border, in a statement on Sunday.

The new location, where construction vehicles have started working, is in the Kurdish-controlled territory and is clearly visible from the Turkish side of the border.

Prime Minister Ahmet Davutoglu had repeatedly said that Turkey would retaliate against any attack on the tomb, Al Jazeera reported.

The Prime Minister's office, in an official statement, said on Sunday that 100,000 square metres of land inside Syrian territory belonged to Turkey in line with international agreements, adding that both the former and new location of tomb still belonged to Turkey.

The tomb, on a site within Syria that Ankara considers sovereign territory as agreed in a 1921 treaty, a 1956 protocol and a 2003 agreement, was relocated close to the Turkish border, while Suleyman Shah's remains were taken to Turkey.

"The new location of the tomb, against the backdrop of this legitimacy [the international documents], is again in the Syrian side of the border. The area where [the] tomb is going to be located is Turkish land although it is outside our borders," the statement said.

A Turkish foreign ministry official told Al Jazeera that the evacuation was necessary as the Islamic State in Iraq and the Levant group and Kurdish fighters have been clashing in the region.
