A total of 157 people were detained over the weekend at unauthorized pro-PKK protests staged in Istanbul, a statement released by the Police Department said on Monday.

The detentions were carried out in Esenyurt, Eyüp, Başakşehir, Beşiktaş, Tuzla, Kadıköy, Üsküdar, Beyoğlu, Şişli, Fatih, Ümraniye, Zeytinburnu, Bahçelievler, Esenler, Gaziosmanpaşa, Sultangazi and Bağcılar districts as protesters attacked police forces with stones, blocked traffic and shouted slogans in support of the terror group.

In addition, four improvised explosive devices and 175 Molotov cocktails were also seized.

Police said 15 cars were set on fire across Istanbul over the weekend while a cluster bomb left on the sidewalk was destroyed by a bomb disposal unit in Istanbul's Beyoğlu district.

The protests come after major developments in Turkey surrounding the detentions of pro-PKK Peoples' Democratic Party (HDP) deputies which were shortly followed by a terrorist car-bomb attack in the southeastern province of Diyarbakır that killed 11 people and wounded more than 100.
