Two people have been killed in a bomb explosion at an outdoor cafe in south-east Turkey, police say.
Three people died in blasts last week
At least seven people were injured in the blast, which hit the tea garden in the town of Catak in Van province, near the border with Iran.
It follows a series of bombings in Turkish resorts and Istanbul last week in which at least three people died.
A separatist militant group, the Kurdistan Freedom Falcons (Tac), has said it carried out those attacks.
It warned on its website on Tuesday that it would turn "Turkey into hell".
The group, which is said to be linked to the outlawed Kurdistan Workers Party (PKK), called on foreign tourists not to travel to the country.
Turkish media said a remote-controlled bomb was detonated as police arrived to investigate a suspicious package.
One of the two people killed was a police officer, the state-run Anatolian news agency reported.
A local official said the bomb had been placed in a rubbish bin.
Security has been tightened on Turkey's Mediterranean and Aegean coasts.
The Turkish economy is heavily reliant on tourism, which Kurdish separatists have repeatedly threatened to target.
