After the investigations into the May 31 Kabul's Zanbaq Square blast, the Afghan Ministry of Interior has accused Pakistan's spy agency Inter-Services Intelligence (ISI) of supplying explosives to the Haqqani network.
Both attacks occurred in the Achin District, where United States and Afghan troops have been carrying out an offensive against a local affiliate of ISIS, officials said.
However, Sirajuddin Haqqani, the Afghan Taliban's second-in-command and head of the Haqqani network, denied any involvement in an audio message distributed to the media late on June 11. "The Islamic Emirate [Taliban] is not behind them", he said.
Residents said three more people, including a boy, were injured in the attack.
"Despite the Taliban's categorical denial, the attack bears all the hallmarks of the movement", Borhan Osman of the Afghanistan Analysts Network stated.More news: No longer out of bounds: Trump allies question Mueller probe

Since the Kabul truck bombing, protesters have set up sit-in camps in at least six locations around the capital, including one near the bombing site, demanding the resignation of President Ashraf Ghani's government.
Haqqani also rejected it was behind a recent bombing near the Grand Mosque in western Herat city, which left seven people dead and 16 others wounded. "Peace with Pakistan was our demand and this must be solved between government and government", Ghani said, according to the statement.
The eyewitnesses informed that around Sehri time, Afghan militant, identified as Abu Bakar, was hit by two missiles fired with help of drone.
The US military command in Kabul said it was investigating the reports.
According to the Khaama Press, a spokesperson of the Ministry of Foreign Affairs of Germany said in a statement, "The attack claimed the lives of over 150 people, including two Afghan employees of a security company who were guarding the German Embassy".
