After the attacks, India asserted that Kasab is a Pakistani national based on his confession and other evidences gathered from him. Several reporters visited Kasab's village and verified the facts provided by him. Former Pakistan Prime Minister, Nawaz Sharif confirmed that Kasab was from Faridkot village in Pakistan, and criticised President Zardari for cordoning off the village and not allowing his parents to meet anyone.
Investigative journalist Saeed Shah travelled to Kasab's village and produced national identity card numbers of his parents; soon after they themselves disappeared on the night of 3 December 2008.
Also, the Mumbai Police said that much of the information that Kasab provided had proved to be accurate. He disclosed the location of a fishing trawler, MV Kuber, that the terrorists used to enter Mumbai's coastal waters. He also told investigators where they would find the ship captain's body, a satellite phone and a global-positioning device, which they did.
Despite mounting evidence, Pakistani officials, including President Asif Ali Zardari, initially denied the assertion that Ajmal Kasab was Pakistani. Pakistani government officials attempted to erase evidence that there was a Lashkar-e-Taiba office in Deepalpur. The office was hurriedly closed in the week of 7 December. Moreover, at Faridkot many residents and local plainclothes police appeared to be trying to cover up Kasab's connection with the village. The atmosphere turned hostile, and several reporters who went to Faridkot were intimidated. In early December, dealing a major blow to Pakistan's claims, Kasab's father admitted in an interview that the captured terrorist was his son.
In January 2009, Pakistan's national security advisor Mahmud Ali Durrani admitted to Kasab being a Pakistani citizen while speaking to the CNN-IBN news channel. The Pakistan Government then hastily acknowledged that Ajmal Kasab was a Pakistani, but also announced that Prime Minister Yousaf Raza Gilani had fired Durrani for "failing to take Gilani and other stakeholders into confidence" before making this information public, and for "a lack of coordination on matters of national security."
