State-sponsored terrorism is government support of violent non-state actors engaged in terrorism. Because of the pejorative nature of the word, the identification of particular examples are usually subject to political dispute and different definitions of terrorism.
Afghanistan's KHAD is one of four secret service agencies believed to have possibly conducted terrorist bombing in Pakistan North-west during the early 1980s; then by late 1980s U.S state department blamed WAD (a KGB created Afghan secret intelligence agency) for terrorist bombing Pakistani cities. Furthermore, Afghanistan security agencies supported the terrorist organization called Al zulfiqar since the 1970s–1990s ;the terrorist group that conducted hijacking in March 1981 of a Pakistan International Airlines plane from Karachi to Kabul.
On 24 June 2017, Pakistani army chief Qamar Javed Bajwa chaired a high-level meeting in Rawalpindi and called on Afghanistan to "do more" in the fight against terrorism. According to the ISPR, the attacks in Quetta and Parachinar were linked to terrorist sanctuaries in Afghanistan which enjoyed the "patronage of Afghanistan's National Directorate of Security (NDS) and India's spy agency Research and Analysis Wing."
India has been accused by Pakistan and Sri Lanka of supporting terrorism and carrying out "economic sabotage" in their respective countries.
India's Research and Analysis Wing has been accused of training and arming the Sri Lankan Tamil group, LTTE, during the 1970s when it was not considered a terrorist organization by any country but it later withdrew its support in the 1980s, when the activities of LTTE became serious, becoming the first country to ban LTTE as a terrorist organization. Although the Indian Government banned the group, the LTTE continued to operate freely and continued to have links with RAW until the defeat of the LTTE in 2009. From August 1983 to May 1987, India, through its intelligence agency Research and Analysis Wing (RAW), provided arms, training and monetary support to six Sri Lankan Tamil insurgent groups including the LTTE. During that period, 32 terror training camps were set up in India to train these 495 LTTE insurgents, including 90 women who were trained in 10 batches. The first batch of Tigers were trained in Establishment 22 based in Chakrata, Uttarakhand. The second batch, including LTTE intelligence chief Pottu Amman, trained in Himachal Pradesh. Prabakaran visited the first and the second batch of Tamil Tigers to see them training. Eight other batches of LTTE were trained in Tamil Nadu. Thenmozhi Rajaratnam alias Dhanu, who carried out the assassination of Rajiv Gandhi and Sivarasan—the key conspirator were among the militants trained by RAW, in Nainital, India. In April 1984, the LTTE formally joined a common militant front, the Eelam National Liberation Front (ENLF), a union between LTTE, the Tamil Eelam Liberation Organization (TELO), the Eelam Revolutionary Organisation of Students (EROS), the People's Liberation Organisation of Tamil Eelam (PLOTE) and the Eelam People's Revolutionary Liberation Front (EPRLF). These Indian trained groups later carried out some of the most devastating terrorist attacks in Sri Lanka.
