Turkish police have arrested 12 academics who signed a petition criticising a government campaign against Kurdish militants and calling for peace talks. Local media reported that another nine lecturers were to be detained on accusations of "insulting the state" and "terrorist propaganda" for backing the declaration, signed among others by US philosopher Noam Chomsky and his Slovenian colleague Slavoj Zizek.

Below is the full text of the petition that infuriated President Recep Tayyip Erdogan, leading to the arrests.

As academics and researchers of this country, we will not be a party to this crime!

The Turkish state has effectively condemned its citizens in Sur, Silvan, Nusaybin, Cizre, Silopi, and many other towns and neighbourhoods in the Kurdish provinces to hunger through its use of curfews that have been ongoing for weeks. It has attacked these settlements with heavy weapons and equipment that would only be mobilized in wartime. As a result, the right to life, liberty, and security, and in particular the prohibition of torture and ill-treatment protected by the constitution and international conventions have been violated.

This deliberate and planned massacre is in serious violation of Turkey's own laws and international treaties to which Turkey is a party. These actions are in serious violation of international law.

We demand the state to abandon its deliberate massacre and deportation of Kurdish and other peoples in the region. We also demand the state to lift the curfew, punish those who are responsible for human rights violations, and compensate those citizens who have experienced material and psychological damage. For this purpose we demand that independent national and international observers to be given access to the region and that they be allowed to monitor and report on the incidents.

We demand the government to prepare the conditions for negotiations and create a road map that would lead to a lasting peace which includes the demands of the Kurdish political movement. We demand inclusion of independent observers from broad sections of society in these negotiations. We also declare our willingness to volunteer as observers. We oppose suppression of any kind of the opposition.

We, as academics and researchers working on and/or in Turkey, declare that we will not be a party to this massacre by remaining silent and demand an immediate end to the violence perpetrated by the state. We will continue advocacy with political parties, the parliament, and international public opinion until our demands are met.
