Pakistan’s Prime Minister Nawaz Sharif in an emergency cabinet meeting held today said Islamabad was ready to counter any external threat.
The meeting was held to discuss the situation in Kashmir and the cross-border firing along the Line of Control (LoC) with India.
Sharif called the attack at the LoC "unprovoked and naked aggression" of Indian forces.
"No external force has the capability or capacity to challenge the sovereignty and territorial integrity of Pakistan," he was reported as saying.
Pakistan’s foreign secretary had also earlier summoned the Indian High Commissioner and urged the Indian government "to ensure the safety and security of Pakistan's High Commissioner, other officials and their families, in accordance with the Vienna Convention".
The cabinet condemned “unprovoked firing at the LoC” which claimed the lives of two Pakistani soldiers, Pakistan media reports said.
The Indian Army said it carried out surgical strikes at the LoC on Thursday in response to the attack on an Indian Army base in Uri, Jammu and Kashmir, that killed 19 soldiers earlier this month.
The strikes had been based on "specific credible information" that militants were planning to carry out strikes in Indian cities, including Jammu, Lieutenant General Ranbir Singh of the Indian Army told reporters on Thursday.
But Pakistan has denied India conducting any surgical strikes on their soil.
Islamabad says there was a cross-border "skirmish" between the Indian Army and Pakistan Rangers that killed two of their soldiers.
Pakistan also claimed that they captured one of the Indian soldiers during the exchange over the border.
But New Delhi said the soldier had "inadvertently crossed" over to the other side of the LoC and not captured by Pakistan.
Pakistan Defence recently tweeted that the Indian establishment was nervous that the captured soldier would expose India's 'surgical strikes claim.
Indian military is in complete panic mode by what the captured Indian soldier might reveal about the so called "Surgical Strike" .
