Gunmen believed to be from the Kurdistan Workers\'\' Party (PKK) killed four women and a police academy student in attacks on two police academies in Turkey\'\'s southeast on Tuesday and Wednesday. The PKK attacked a van with guns and hand grenades in the southeastern province of Siirt late on Tuesday, killing four women in the vehicle, according to Siirt Governor Musa Colak. Two other women in the van were also injured. One of the assailants was also killed when a grenade exploded prematurely in his hand. The attack occurred close to Siirt\'\'s police academy, leading to speculation that the assailants may have mistaken the van for a police vehicle, Turkish (Today\'\'s Zaman) news reported. In another attack, the PKK targeted a police academy in Bitlis, killing a student and injuring five others. A large-scale operation was launched in the province to capture the assailants.
