Four policemen were martyred when a blast ripped through a market in Quetta's Satellite Town on Monday night, according to Quetta Deputy Inspector General (DIG) Police Abdul Razzaq Cheema.

The DIG said that two policemen and seven civilians were injured in the blast, and that a police van was damaged.

The blast, according to DIG Cheema, was the result of an improvised explosive device (IED) planted in a motorcycle parked on the roadside.

The injured were shifted to the Civil Hospital, where an emergency was imposed. Security officials, meanwhile, cordoned off the area.

It is the fourth act of violence in the country since the holy month of Ramazan began. On May 8, five policemen were martyred in what officials described as a suicide bombing targeting an Elite Force van detailed to the security of the Data Darbar shrine in Lahore.

Later the same day, three people, including a tribal leader named Wali Khan Achakzai, were killed in a blast in Killa Abdullah.

Today's blast comes two days after a terrorist attack on Pearl Continental Hotel, Gwadar in which three people were killed while four were injured.

Condemnations pour in

PML-N President Shahbaz Sharif condemned the blast in Quetta, saying that "by targeting Balochistan multiple times the enemy has made its intentions clear."

Sharif said "the surge in terrorism incidents is worrisome" and paid tribute to the security officials for "risking their lives in defence of the country and its people".

"The entire nation stands determined until the eradication of terrorism," he added.

Jamaat-i-Islami (JI) chief Sirajul Haq also condemned the incident, saying that "terrorists are the enemies of humanity and do not belong to any religion."

He urged security organisations to "stay alert as terrorism is rearing its head again".
