IZMIR: Turkish police increased security at tourist resorts on Sunday as investigators sifted through the wreckage of a minibus ripped apart by a bomb that killed five people, including a British and an Irish woman. In the normally bustling Aegean resort of Kusadasi, the site of Saturday's blast, locals and tourists were uneasy and streets were quieter than normal after the second attack to hit the area in a week at the height of the tourism season. A Turkish daily said a Kurdish militant group, TAK, claimed responsibility for the attack, but this could not be confirmed. It has claimed a series of bombings in the last year, including an attack which injured 20 in the same region six days earlier. British Ambassador Peter Westmacott, visiting the injured in hospital, told the BBC authorities believed the Kurdistan Workers Party (PKK), the main guerrilla group, had planted the bomb. A top PKK official condemned the attack in a statement.
