Pakistan: Above 50 killed in Wagah blast

The blast occurred after the flag- lowering ceremony at the Indo-Pak land border crossing, reports said.

According to reports,militant groups Jundullah and Jamaat-ul-Ahrar  have claimed responsibility for the attack.

The newly formed Jamaat-ul-Ahrar group of TTP also claimed the Wagah border attack as its spokesman Ehsanullah Ehsan, speaking to Dawn on telephone from Afghanistan, said it was carried out by one of their men.

"We will continue such attacks in the future," Ehsan told Dawn News.

"Some other groups have claimed responsibility of this attack, but these claims are baseless. We will soon release the video of this attack," he said.

"This attack is revenge for the killing of those innocent people in North Waziristan," the banned militant group's spokesman said. 

Reacting on the incident, Maryam Nawaz Sharif, daughter of country's Prime Minister Nawaz Sharif, tweeted: "Wahga suicide attack: Prime Minister instructs Interior Minister to provide every assistance needed."

"Wahga border blast is perhaps the biggest hit-back ever since the operation started. Insha'Allah this will end and Pak will see peace," she said.

Meanwhile, Indian Prime Minister Narendra Modi has condemned the attack.

"Terror attack in Pakistan near Wagah Border is shocking. I strongly condemn such a dastardly act of terrorism.My condolences to the families of the deceased. Prayers with the injured," Modi tweeted.
