JuD chief Hafiz Mohammad Saeed, mastermind of the Mumbai attacks, on Sunday alleged that India has "imposed war on Pakistan" by constructing "illegal dams" and diverting water of Pakistani rivers and said the government must prepare the nation to counter this aggression.
Saeed made the remarks while launching a "nation-wide protest" against what he described as India's "theft" of Pakistan's share of river waters.
A declaration adopted at the rally said: "If India continues with her water terrorism, Pakistan must keep open the option of using force."
It alleged that India had "virtually declared war on Pakistan by unlawfully constructing dams and diverting Pakistani rivers".
"We also call upon our government to build unity among various religious, political and civil society groups so that we stand solid behind the Pakistan Army as India is, in fact, preparing to impose war on Pakistan," the declaration claimed.
The declaration contended that Kashmir is a disputed territory according to UN resolutions and called on the UN and the world community to take "immediate notice of controversial Indian projects in a disputed territory and force India to stop this aggression that may trigger war between two nuclear armed neighbours".
