Turkey's outlawed Kurdistan Workers' Party (PKK) on Tuesday claimed responsibility for the killing of a local politician from the ruling Justice and Development (AKP) party in the restive south-east of the country.

The Anadolu state news agency reported Tuesday that Deryan Aktert, the AKP chief of the district of Dicle, in Diyarbakir province, was shot dead the night before.

A statement on a PKK-affiliated website said the attack was carried out to punish the politician for taking part in the "massacre of our people by the fascist AKP state."

On Sunday, another AKP local official, Aydin Mustu, was killed in the province of Van, Anadolu said.

The AKP has described the second deadly attack in two days on its local politicians in the Kurdish region as an attempt at intimidation.

The ceasefire between the PKK and the government collapsed last year. Since then, more than 2,000 people - including civilians, members of the security forces and militants - have been confirmed dead in renewed violence.

Turkey deems the PKK a terrorist group. The PKK says it is demanding greater autonomy and rights for the Kurdish minority in Turkey, which is discriminated against.
