The Turkish parliament has again extended the deployment of the military in Syria and Iraq.
The parliamentarians in Ankara voted for a continuation by two years until October 2023, as the state news agency Anadolu reported on Tuesday evening.
In northern Iraq, the Turkish army is repeatedly attacking targets of the banned Kurdish Workers' Party PKK, which has its headquarters in the Kandil Mountains, with air and ground offensives.
In the past, the Scientific Service of the Bundestag had expressed doubts as to whether the mission was compatible with international law.
Turkish troops have invaded northern Syria several times since 2016 and are occupying areas in the border region.
Ankara is fighting the YPG there - the government regards the Kurdish militia as a Syrian offshoot of the PKK.
In Syria, however, the YPG is also the USA's most important ally in the fight against the terrorist militia Islamic State (IS).
The vote came from the ruling AK party of President Recep Tayyip Erdogan.
Together with its government partner, the ultra-nationalist party MHP, it has a majority in parliament.
MPs from both parties as well as MPs from the opposition nationalist Iyi party voted for the operation, Anadolu reported.
The MPs of the Kemalist CHP and the pro-Kurdish HDP had voted against.
It had previously been criticized that the assignments should be extended by two years instead of - as has been the case up to now - by one year.
