The Hindu Sena Rashtriya Sangh Party was most likely the creation of right-wing individuals in India, and had no actual connection to the attack in Islamabad.  If the group did exist, it has not claimed responsibility for an attack since the bombing and can be considered inactive.

Hisba is the name used to refer collectively to gangs of Islamic fundamentalist vigilantes in Northern Nigeria, who take it upon themselves to oversee the implementation of Islamic law, or Sharia, in the region.  After years of violence between different religious and ethnic groups, the Nigerian central government has opted to allow the Northern part of the country to adopt Sharia.  In Sharia states such as Kano, the Hisba can reprimand, arrest, or even beat Nigerians caught violating the law.  Punishable offenses include drinking or selling alcohol, having premarital sex (most often revealed when the women gets pregnant), or soliciting a prostitute.  Hisba members also ensure that the buses in Northern Nigeria are segregated by gender.  Although the methods of the Hisba are often violent and arbitrary, the military and official police turn a blind eye towards their activities.  Nigerian President Olusegun Obasanjo has declined to interfere in either the Sharia controversy, or the Hisba issues, because of the intense emotions on both sides.

The goals of the Hisba are unchanging; they seek to ensure that Sharia is implemented faithfully and completely in the states that have adopted it.  They continue to believe that violence is an effective means of achieving those goals.  For example, in April 2001, a Hisba gang destroyed hotels in a Christian area of the city of Kano on suspicion that the hotel had been selling liquor.

Funded by the United States during the Afghan-Soviet War, current source of funding unknown

Emerging in 1977, Hizb-I Islami Gulbuddin (HIG) is a radical faction of the Hizb-I Islami party that seeks to liberate Afghanistan from the influence of foreign forces, overthrow the Afghan government, and establish a fundamentalist Islamic state.<br /><p><br />Based in Eastern Afghanistan and the tribal areas in Western Pakistan, HIG was known to be one of the most radical mujahideen groups in the Afghan resistance during the Soviet occupation. The group had close ties to the Taliban and Osama bin Laden during this period, and the Taliban and al-Qaeda continue to operate in the same spheres as HIG. Though anti-American in principle, Hikmatyar displayed pragmatism in accepting millions of dollars worth of American funding and equipment to help the mujahideen fight the Soviets in Afghanistan.<br /><p><br />In the early 1990s, HIG founder Gulbuddin Hikmatyar was known to have operated several terrorist training camps in Afghanistan. After training, terrorists would be sent to assist mujahideen in other hotbeds of religious conflict. Following bin Laden's expulsion from Sudan in 1996, Hikmatyar offered bin Laden safe haven.<br />
