Battle of Tora Bora (2017)

The Battle of Tora Bora in June 2017 was a military engagement for the cave complex of Tora Bora and its surroundings in Afghanistan. Fighting took place between the Islamic State of Iraq and the Levant – Khorasan Province (ISIL-K) and forces opposed to it, namely the Taliban, militias formed by the population of the Pachir Aw Agam District, and the Afghan National Army. After heavy clashes ISIL-K forces initially succeeded in capturing Tora Bora from the Taliban on 13-14 June 2017, but Afghan government forces retook the cave complex by 17 June.

Background


Although Tora Bora, former stronghold of Osama bin Laden, was cleared of Taliban forces during a United States-led operation in 2001, the militant group soon retook the mountain stronghold. Since then, Tora Bora has functioned as important base for the Taliban insurgency, while the area around it mostly fell under the group's influence. The Taliban's control over much of Nangarhar Province's hinterland was challenged upon the foundation of ISIL-K in 2015, however, and the two militant organizations began a brutal conflict for dominance. Meanwhile, the Afghan government's control in these remote areas was mostly limited to some outposts and population centers. Nevertheless, pro-government self-defense groups and tribal militias did emerge to fight against all insurgent groups in the area.

The Pachir Aw Agam District, where Tora Bora is located, was home to both Taliban as well as government followers, and thus quickly became a target for ISIL-K, which began to terrorize the district's population through killings, abductions, raids and looting. As result, the locals became extremely hostile and opposed to ISIL-K. On 13 April 2017, the United States bombed and largely destroyed the cave systems in Achin District that were used by ISIL-K as main base. As result, the group was deprived of its sanctuary; according to Afghan politician and former warlord Hazrat Ali, this caused ISIL-K to seek a new refuge. Probably due to its strategic location the Islamic State militants chose Tora Bora as prospective new headquarters, and moved to capture it from the Taliban.

ISIL-K capture of Tora Bora


ISIL-K began its offensive to capture the mountain stronghold on 6 June with allegedly up to 1,000 militants. The head of the Afghan National Directorate of Security in Nangarhar Province accused Pakistan of supporting the ISIL-K offensive. After the Islamic State fighters began to assault the Taliban positions, local militias joined the fight against ISIL-K. Although they traditionally supported the government and opposed the Taliban, these militias saw ISIL-K as greater threat due to the group's brutal reputation. It remains unclear, however, whether the militias directly aided the Taliban or operated separately. In consequence of the resulting clashes, about 500 families were displaced. After three days of heavy fighting in the mountains, the first ISIL-K assault was beaten back by the Taliban and pro-government forces. Suffering "dozens" of casualties, the attackers were forced to scatter and retreat.

Despite this setback, ISIL-K soon regrouped and renwed their offensive. Calls by the locals for the government to provide aid to them went unheeded, and on late 13 June the Islamic State fighters eventually managed to capture much territory around Tora Bora after fierce fighting against both the local militias as well as the Taliban. On early 14 June, the Taliban defenses at the mountain stronghold completely collapsed, and the group's fighters fled from the area. Without the Taliban forces to support them, the local militias of Tora Bora were no longer able to hold their lands, and also retreated, taking their families with them. Though both Taliban as well as some pro-government sources denied that all of Tora Bora had fallen to ISIL-K, and maintained that Taliban elements still held out in the region, local villagers as well as the Afghan military reported that the Islamic State forces had set up their flag and heavy artillery on the mountains over Tora Bora.

After taking control of Tora Bora, ISIL-K proceeded to advance against the government in the wider Pachir Aw Agam District, with one commander of the group stating that "We are in Tora Bora but this is not the end. The plan is to take more territory from the government and the Taliban." According to a local reporter of Voice of America, the whole district was on the verge of collapse. ISIL-K began to propagate its victory at Tora Bora on its Radio Khilafat, while urging locals who had fled to return to their homes. According to security analyst and counter-terrorism expert David Otto, however, the area around Tora Bora was so hostile to ISIL-K and the Taliban so entrenched there that the former group would not be able to hold it for long.

Government offensive
Before the Taliban could launch a counter-attack, however, President Ashraf Ghani ordered the Afghan National Army's 201st Corps to launch their own offensive against Tora Bora on 14 June. The army quickly moved against ISIL-K, and by 16 June had reportedly begun to push the militants back. On the next day, the Afghan National Army stormed the Tora Bora cave complex from the foot of the mountains, while Commandos were airdropped onto the mountain peaks. The stronghold quickly fell, while the Afghan government forces proceeded with clearing operations in the area and its surroundings. On 25 June, the Afghan Ministry of Defense officially declared that ISIL-K had been completely evicted from the area around Tora Bora, and that the cave system would be turned into a military base of the Afghan military.

Aftermath
In July 2017, the Afghan National Directorate of Security financed and armed a new militia of around 300 locals from Pachir Aw Agam District to combat ISIL-K in the area around Tora Bora. Meanwhile, ISIL-K had renewed its operations in the Tora Bora region, reportedly raiding and destroying local Taliban outposts.
