Islamabad, Pakistan (CNN) -- Two bomb blasts in different parts of southwest Pakistan killed 12 people and injured 25 Thursday, officials told CNN.
More than 55 pounds of explosives were packed into a rickshaw near a hotel near a crowd of people in the city of Sibi in Balochistan, Ghullam Ali Lashari, a local police officer, told CNN.
The explosion killed nine people and injured 23.
"The strength of blast also damaged nearby houses and shops," Lashari said.
In the second blast, three security personnel were killed and two were injured in Dera Bugti district in Balochistan, said Murtaza Baig, a paramilitary force spokesman.
A landmine was planted on a road used by security personnel for routine patrols around gas installations in the area, Baig said.
There was no immediate claim of responsibility for the incidents.
Balochistan province has Pakistan's largest reserve of gas and has seen violent clashes between suspected insurgents and security forces in the past few years.
