Gunmen hurled a hand grenade and fired at the home of a lawyer in southwestern Pakistan, wounding him and four of his family members, police said on Saturday.
No one immediately claimed responsibility for the attack late on Friday at the home of Mohammed Rafique in Quetta, the capital of Balochistan province, and a senior police official, Wazir Khan Nasir, said officers were still investigating.
The attackers fired a single shot that injured Rafique, he said, adding that as the lawyer's panicked family members tried to take him to hospital the gunmen threw a grenade and escaped.
Nasir said police later transported the wounded to a hospital where they were in a stable condition.
The motive behind the attack was not known, and the lawyer was not handling any politically sensitive cases, according to the police.
Rival tribes in Balochistan have been fighting for decades with the Pakistani government and each other demanding autonomy and control over royalties from natural gas fields in the region.
