A senior commander of the Pakistani Taliban has claimed responsibility for the attack near the country's border with India.
Two Taliban suicide bombers attacked the Afghan capital this morning, killing at least seven people and wounding more than 15, government officials said.
The Taliban, fighting to oust foreign forces and the US-backed government, claimed responsibility for the attacks in the east and west of Kabul.
"Double martyrdom attack has rocked #Kabul city this morning amid current year's ongoing #Khaibar operation," the Taliban said on Twitter, referring to their yearly summer fighting offensive.
Officials from Afghanistan and the United States signed a deal on Tuesday allowing American troops to stay in the country after the end of the year, filling a campaign promise by new President Ashraf Ghani.
A group of Taliban militants responsible for shooting Malala Yousufzai, a teenage activist targeted for her campaign against the terrorist group's efforts to deny girls education, have been arrested, Pakistan's army said.
Taliban activists claimed responsibility for shooting Malala in 2012 for her advocacy of women's right to education but no one had been arrested until now.
Two other schoolgirls were also injured in the attack.
The Pakistani army's head of press Asim Bajwa told reporters 10 attackers had been identified and arrested.
Malala survived the attack after being airlifted to Britain for treatment and was nominated for the Nobel Peace Prize last year.
The Pakistani army has launched what it calls a "comprehensive operation" to wipe out Islamist militants in the North Waziristan region.
It follows last week's attack on an airport in the city of Karachi, for which the Pakistan Taliban claimed responsibility.
An air strike on militant bases last night was claimed to have killed about 100 militants, many of whom are thought to have been foreign fighters.
"Our valiant armed forces have been tasked to eliminate these terrorists regardless of hue and colour, along with their sanctuaries," the army said in a statement.
Around 100 militants have been killed in nothwestern Pakistan after military jets carried out air strikes on militant hideouts in the North Waziristan tribal area this morning.
Pakistani air force jets targeted eight militant hideouts in the region, according to unidentified intelligence officials.
Many of the dead were believed to be Uzbeks and other foreign fighters, who had been meeting to discuss a deadline given by authorities for militants to leave the area, said two of the Pakistani officials.
The information could not be independently verified.
Released Taliban captive Sgt. Bowe Bergdahl has been taken to the Brooke Army Medical Centre in Texas where he will begin the next phase of his "reintegration process", the Pentagon said.
In a statement released by Pentagon Press Secretary Rear Adm. John Kirby, he said:
"Secretary Hagel is confident that the army will continue to ensure that Sgt. Bergdahl receives the care, time and space he needs to complete his recovery and reintegration."
US army Sgt. Bowe Bergdahl, freed by the Taliban after five years in captivity, has arrived at a Texas military base, the Pentagon has said.
Bergdahl has been recovering in Germany and is now due to be taken to the Brooke Army Medical Centre for treatment.
The FBI is investigating threats against the family of former Taliban prisoner Sgt. Bowe Bergdahl.
The threats come after a number of former comrades of Bergdahl made television appearances accusing him of being a "deserter".
His home town was forced to cancel plans for a welcome-celebration for the soldier, who has been released after five years of captivity in Afghanistan, due to security concerns.
Hailey, Idaho, a town of 8,000, where Sgt Bergdahl's parents, Bob and Jani Bergdahl, live, has been swamped with hate mail and angry calls. FBI spokesman William Facer said:
"The FBI continues to monitor the situation in Hailey, Idaho. We are working jointly with our state and local partners and taking each threat seriously."
The former pastor of the parents of a US soldier released from Taliban captivity after nearly five years says they have been "really hurt" by claims that he was a traitor and the outpouring of anger towards their family.
Pastor Phil Proctor of Sterling Presbyterian Church in Sterling, Virginia, said Bob and Jani Bergdahl were surprised by interviews they had seen with former platoon mates of their son Bowe.
Proctor said the Bergdahls, who live in Idaho, have yet to speak to their son, who is currently recovering at a military hospital in Germany.
Hillary Clinton's new book has revealed that Barack Obama's government demanded the release of captured US soldier Sgt Bowe Bergdahl in every prisoner discussion it held with the Taliban.
The former US secretary of state also says in her book, Hard Choices, that she recommended President Obama end the decades-long US embargo on Cuba to force Fidel and Raul Castro into democratic change.
