Pakistan has been hit by another bomb attack, this time in Balochistan province, a day after twin bombings killed dozens of people in Karachi.

On Saturday, twelve people were injured in the city of Quetta when a remote-controlled bomb targeting a security convoy was set off.

Police say the bomb had been planted on a motorbike.

No one has claimed responsibility for the attack.

The incident comes a day after two bomb attacks killed at least 33 Shia Muslims and injured 170 in Karachi. On Saturday, thousands of mourners attended the victims' funerals.

Pakistan has experienced a wave of violence over the past two years in which nearly 3,000 people have been killed in bomb attacks and other terrorist operations across the country.
