Police say the son of Pakistan’s president has escaped a roadside bomb attack unharmed after the blast killed three people and wounded 15.

The attack happened late Sunday in Pakistan’s restive Baluchistan province, long home to a low-intensity insurgency.

Police officer Ghulam Rasool says the bomb, planted on a motorcycle and detonated by remote control, exploded in the province’s Hub industrial area as a vehicle carrying Suleman Mamnoon Hussain passed by.

Rasool says the dead and most of the wounded were pedestrians, though some police officers accompanying Hussain were wounded.

His father, Pakistani President Mamnoon Hussain, took office in September 2013. No group immediately claimed responsibility for Sunday’s attack, though Taliban extremists have been waging a long war in the country. Baluchistan separatists also have launched attacks in the province.
