A senior Afghan official has accused some elements within the Pakistani military of being behind a recent wave of devastating blasts in the Afghan capital, Kabul, Press TV reports.  

Abdul Haseeb Siddiqui, a spokesperson for the Afghan intelligence service National Directorate of Security (NDS), said on Wednesday that some elements within the Pakistan military were behind the recent deadly bombings in the Afghan capital that killed more than 50 people.

Siddiqui alleged that Pakistan has been engaged in fighting a proxy war through the Taliban militants across Afghanistan.

The spokesman also said Afghan forces will not relent in the battle against militancy and that they will defend the country against terrorists.

The remarks come two days after Afghan President Ashraf Ghani blamed the government in Islamabad for the recent deadly terrorist attacks in Kabul.

"The last few days have shown that suicide training camps and bomb-producing factories which are killing our people are as active as before in Pakistan," Ghani told a press conference on Monday, adding, "We hoped for peace, but we are receiving messages of war from Pakistan."

The Afghan president also said he had once again asked Pakistani Prime Minister Nawaz Sharif to take serious action against the growing activities of terrorist groups in Pakistan, which directly target security and stability in neighboring Afghanistan.

On August 7, a string of deadly terrorist attacks struck the US military base of Camp Integrity, an army compound and an Afghan police academy. A total of 51 people were killed and hundreds of others were injured in the triple attacks.

In early July, Dawlat Waziri, the deputy spokesman for the Afghan Defense Ministry, alleged that Pakistani helicopters had airdropped weapons to the Taliban militants in the troubled eastern province of Paktika. According to Afghan sources, the Pakistani helicopters were dropping weapons to Taliban in the Barmal district of the province.

The relations between Kabul and Islamabad are traditionally mired in distrust. Afghanistan and Pakistan blame each other for the Taliban violence plaguing both countries.

Tensions have risen along the Afghan-Pakistani border in recent months.

Kabul blames elements inside the Pakistani spy agency Inter-Services Intelligence (ISI) for supporting the Taliban militants, while Islamabad blames the Afghan government for giving refuge to militants on its side of the border.

Helmand provincial council member Bashir Ahmad Shakir said on Wednesday that at least 15 Afghan policemen lost their lives after they were attacked by a heavily-armed group of Taliban militants in Musa Qala district of Afghanistan's southern province of Helmand earlier in the day.
