4 injured in explosion near police HQ in Turkey's Diyarbakir

CAIRO – 11 April: A strong blast rocked Turkey's Diyarbakir city on Tuesday, near the riot police headquarters, AFP reported.

At least four people were wounded in the blast which could be heard in several areas of the southeastern city, which has the largest concentration of Kurds in the country. The cause of the explosion was not immediately known.

The explosion occurred just days before a key referendum on boosting President Recep Tayyip Erdogan's powers.

Turks will on Sunday vote on whether to approve constitutional changes giving Erdogan executive presidential powers, which critics say would drag the country into one-man rule.
The southeast has been battered by renewed fighting between Kurdish rebels and Turkish security forces since a fragile truce collapsed in summer 2015.
