In an interview to The Associated Press, Musharraf said Sarabjit had "carried out terrorist attacks and killed people" in Pakistan, but the President added he would look into the legal aspects of the case.

"One has to take the decision in a deliberate manner," he said, adding, "It needs to come to me with all its legal implications, then only will I take a decision. But I am basically a person who shows compassion and mercy."

Sarabjit, who Pakistan claims is Manjit Singh, has been sentenced to death for his alleged involvement in the 1990 bomb blasts in Lahore and Multan.

Sarabjit's family denies he was a Research and Analysis Wing agent as claimed by Pakistan and insists he strayed accidentally into Pakistani territory while farming his land. His wife and two daughters have threatened to commit suicide unless his life is spared.
