QUETTA: Militants continued to target electoral offices and proposed polling stations in different parts of Balochistan on Friday.

At least five persons were injured when militants targeted the electoral office of a Pakistan Peoples Party (PPP) candidate in the Brewery area of Quetta, the capital of Balochistan, on Friday morning, police said.

According to the police, militants had planted an Improvised Explosive Device (IED) on the roof of the electoral office of Sardar Umar Gorgage, a candidate of former ruling party PPP. The blast damaged the office and injured five PPP workers.

In another incident, militants blew up three polling stations in Balochistan's troubled district Dera Bugti.

Ayaz Baloch, a levies official, told Dawn.com that militants blew up three proposed polling stations in the Sui town of Dera Bugti. However, no human loss was reported.

Meanwhile, militants fired two rockets on two polling stations in the Panjgoor area of Balochistan.

Barakat Baloch, a levies official, said there was no human loss.

Militants also hurled a petrol bomb at the office of Balochistan National Party Mengal (BNP-M). No human loss was again reported.

Moreover, a wheel jam and shutter down strike was observed in almost all of the Baloch dominated areas of Balochistan.

The Baloch National Front (BNF) had given call for strike on the eve of elections on account of their opposition towards elections in Balochistan.

BNF supporters blocked national highways linking Pakistan with Iran, and Balochistan with neighbouring Sindh and Punjab provinces.

All shops and business centers remained closed on second consecutive day of BNF's continued strike.
