India has supplied Pakistan with intelligences, such as against the perpetrators of a terrorist attack.

such as 表示“列举”前文事项，本句其实省略的还是 intelligences，因为重复而省略，我们可以用替代词those 代替，against 短语作定语。完整说法是：

India has supplied Pakistan with intelligences, such as those against the perpetrators of a terrorist attack.

印度向巴基斯坦提供了情报，例如针对恐怖袭击肇事者的情报。
