Four civilians killed, 19 other people, including five police officers, injured in bomb attack at a police vehicle on Monday in southeastern Silopi district of Sirnak province of Turkey, Dogan News Agency reported.

The outlawed Kurdistan Workers' Party (PKK) militants placed explosives under manhole cover and detonated with remote control while a police vehicle was passing, the agency reported.

In a separate incident, two police officers were killed, another injured on Monday in a bomb attack by the PKK members in eastern Van province, according to Dogan News Agency. The bomb was exploited by remote control targeting an armored police car.

Since a two-year cease-fire between the government and the PKK disintegrated last July, Turkish security forces have launched a major campaign against the group in southeast Turkey, leaving over 450 government soldiers and over 3,700 PKK members dead.

Ankara accused the PKK of waging a separatist war since 1984. The group is listed as a terrorist organization by Turkey, the United States and the European Union.
