Afghanistan’s National Directorate of Security (NDS) said in a statement on Monday that its forces detained at least four top militants during a raid on a militant hideout in the 8th police district of the Kabul city.
The militants had intended to carry out a string of deadly attacks on Afghan presidential place, Defense Ministry and two US-led NATO bases across the troubled city, it noted.
The statement also said the militants had received military training inside Pakistan's northwestern tribal region near the border with Afghanistan.
The developments come as relations between Kabul and Islamabad are traditionally mired in distrust. Afghanistan and Pakistan blame each other for the Taliban-led violence plaguing both countries.
Senior officials in Kabul blame elements within the Pakistani spy agency Inter-Services Intelligence (ISI) for supporting Taliban militants, while Islamabad blames Afghanistan for sheltering militants.
In a separate development, an Afghan soldiers was killed and two others injured in an explosion while defusing a landmine in Pashton Zarghon District of western Herat Province.
Meanwhile, at least five people were killed after Afghan forces attacked a gathering of the Taliban militants mourning the death of their deceased chief Mullah Omar in central-eastern city of Ghazni.
The US-led NATO forces invaded Afghanistan in 2001 with the stated objective of curbing militancy and bringing peace and stability to the region. However, after nearly 14 years, the region is still grappling with rampant militancy.
