QUETTA/CHARSADDA  - Militants lobbed grenades at two small businesses and a private school in three separate attacks in Quetta and Charsadda on Wednesday, killing at least six people and wounding 11, officials said.
The first two incidents, which police said were ethnically-motivated, took place in Quetta. They killed five people and wounded 10.
A female teacher was killed and a girl wounded in the third attack, which took place at a co-education school in Charsadda where the Taliban are violently opposed to secular education.
In the first attack a grenade exploded in a crowded barber’s shop in the main market of Quetta.
“Four people riding two motorbikes arrived at the salon on the main double road of the city and lobbed two grenades on the shop,” said Aitezaz Goraya, a senior police official.
“After the grenade attack, they fired shots at the people present at the shop,” he added.
Thirteen people were injured in the attack and later four of them succumbed to their injuries while receiving treatment at a local hospital.
However, police sources said the suspects opened fire at two barber shops on Double Road in Langoabad area.
The attack damaged two shops which were reportedly crowded at the time of incident. The injured were shifted to Quetta Civil Hospital where two victims succumbed to their injuries.
Fear and panic gripped the area after the incident. Law enforcement personnel have sealed Double Road and launched search operation in the area to nab the culprits.
According to police, the shop owners belonged to Bahawalpur and authorities had already alerted them that they could be targeted by the miscreants. 
Further investigation into the incident is underway.
The second attack targeted a photo studio in Zamindar Street on Quetta’s Sariab Road.
“One person was killed and another got injured in this attack,” said Imran Qureshi, a senior police official in the area.
Police said both businesses were probably attacked because they were owned by Punjabis.
No group immediately claimed responsibility but Baloch separatists are active in the area. They often attack government forces, installations and people who have been settled in Balochistan from Punjab.
In the third attack, also on Wednesday, unidentified militants hurled two grenades at a private school in Shabqadar Bazaar of Charsadda district, killing a female teacher and wounding a girl.
Locals said unidentified terrorists lobbed grenades into the Askari Foundation School and College at 12:45pm. Resultantly, a lady teacher, Hina Javed, and a student Laila got multiple injuries. The grenades exploded outside the class.
The injured were rushed to the Tehsil Headquarters Hospital Shabqadar where the teacher Hina Javed succumbed to her injuries, they said. The injured student Laila was under treatment at hospital.
Shafiullah Khan, a senior police officer, said the attack happened at the end of the school day when teachers were sitting in the staffroom.
Locals said at least two grenades were hurled at the school, which is situated at Katozai Road in Shabqadar.
Police rushed to the site after the incident, however, the attackers managed to flee after committing the crime.
Shabqadar Police Station registered a case against unidentified men on the complaint of Brigadier (R) Behramand, the principal of the school, who was present at the school at the time of the incident.
