Kulbhushan Jadhav, who was arrested in March 2016, had been convicted by a military tribunal, the Pakistani army said in a statement. General Qamar Javed Bajwa, the head of Pakistan’s armed forces, signed off on the sentence.
‘‘Anyone who patronizes our killers will be met with iron hands,’’ he told the local Geo TV channel. ‘‘We have no mercy for them.’’
Islamabad alleges that Jadhav was an Indian intelligence official who aided and financed terrorist activities in the southwestern province of Baluchistan and the southern port city of Karachi.
India’s foreign office summoned Abdul Basit, the Pakistani High Commissioner to Delhi, to register a formal complaint.
The External Affairs Ministry issued a statement dismissing Jadhav’s trial as a farce and saying Pakistan had ignored 13 separate requests in the past year to be permitted to offer him consular services.
