Speaking to reporters, Antony said, "US decision to provide sophisticated weapons (to Pakistan) is a matter of serious concern to India. The US should ensure that these weapons are not targeted against India."
Antony noted that the issue had already been taken up with the US Defence Secretary during his visit to India recently.
He said, "The American explanation that Pakistan army has to be strengthened to fight terrorist outfits like Al-Qaeda and Taliban in Afghanistan was not convincing to India."
"This is a matter of concern to India and I hope that the US will take a serious note of this," Antony said.
He said while India preferred to carry on talks with Pakistan, Islamabad should take firm action to dismantle as many as 42 terrorist camps operating on its soil.
"Unless these terrorist camps are destroyed, it is a difficult situation. We want some action (by Pakistan) to dismantle these camps," he added.
