Congress MP Shashi Tharoor on Tuesday slammed Pakistan for the death sentence on alleged Indian spy Kulbhushan Jadhav, terming it an "assault" on international laws and conventions.
"What Pakistan is doing is not only an assault on India, it is an assault on international laws, international conventions that affect everybody.
"There are certain countries that finance and arm the Pakistani military. Those countries must be told by us that if this can be done to an Indian today, it can be done to one of their nationals tomorrow," Tharoor said in the Lok Sabha.
"The extremely important thing for us is to uphold the principles. Thirteen times this gentleman was denied consular access, which is a basic right.
"Geneva conventions have been violated by Pakistan... This is an extremely serious matter," he added.
The opposition and the treasury benches in Parliament on Tuesday jointly expressed solidarity with Jadhav, who was awarded capital punishment by a Pakistani Field General Court Martial on Monday.
India has warned Pakistan that bilateral ties will be hit if it goes ahead with the death sentence.
