At least four Pakistani soldiers were killed and 10 others were wounded on March 15 when an improvised explosive device detonated near a convoy of security forces in southwestern Pakistan, officials said.
No one immediately claimed responsibility for the attack in the Balochistan Province's Sibi district.
Local officials told RFE/RL that security forces cordoned off the area and rescue services transported wounded and the dead to the hospital by helicopter.
At least seven security personnel were killed and 25 were wounded a week ago in a suicide attack in Sibi, just minutes after Pakistani President Arif Alvi attended a cultural event in town.
The Islamic State extremist group claimed responsibility for the March 8 suicide attack.
Resource-rich Balochistan, Pakistan's largest and most volatile province, borders Afghanistan and Iran.
It has been plagued by sectarian violence, attacks by Islamist militants, and a long-running separatist insurgency that has led to thousands of casualties since 2004.
