The protesters in Quetta, the capital of the southwestern Baluchistan province, called on the government to take action to dismantle the IS affiliate, which has a growing presence in South Asia alongside the Taliban and other extremist groups.
The suicide attack on Friday, which killed 28 people, targeted Abdul Ghafoor Haideri, deputy leader of Pakistan's Senate, who narrowly escaped the blast.
Haideri's Jamiat-e-Ulema Islam is a pro-Taliban Islamist party that is allied with the ruling party of Prime Minister Nawaz Sharif, illustrating the Pakistani government's complex ties to Islamic extremists, some of which it views as allies in regional power struggles with Afghanistan and India.
In neighboring Afghanistan, an Islamic State affiliate is at war with both the US-backed government and the Taliban, with whom it is bitterly divided over leadership and tactics. Friday's bombing was likely directed against the Taliban.
Rallies protesting Friday's attack were also held in other parts of Pakistan, said Hafiz Hamdullah, an aide to Haideri.
Another two paramilitary troops were wounded today in a roadside bomb attack in Quetta city.
Lashkar-e-Jhangvi, another extremist group considered close to IS, claimed responsibility for both attacks.
