Prime Minister Narendra Modi has accused Pakistan of creating "nuisance" and "constantly" troubling India by promoting terrorism during a rare scathing attack on the nuclear-armed neighbour from foreign soil.
The Prime Minister's sharp criticism came during the course of his address at the Bangabandhu International Convention Center in Dhaka when he vowed with Bangladesh to jointly combat terrorism in the region.
"Pakistan aaye din (every now and then) disturbs India, jo naako dum la deta hai (creates nuisance), terrorism ko badhawa (deta hai)... ki ghatnaayein ghatthi rehti hain (promotes terrorism and such incidents keep recurring)," PM Modi said in his address to Dhaka University on Sunday.
Recalling that 90,000 Pakistani prisoners of war were in India's captivity during the 1971 Bangladesh Liberation War, PM Modi said, "If we had a diabolic mindset, we do not know what decision we would have taken."
"Terrorism has no boundaries. India has been troubled by it for the last 40 years. So many innocent people have died and what did those associated with terrorism gain and what have they given to the world... Terrorism has no values, no principles, no traditions and it has only one motive and that is enmity against humanity," he said.
A joint declaration issued on the last day of PM Modi's maiden two-day visit to Bangladesh reaffirmed the two countries' "unequivocal and uncompromising position against extremism and terrorism in all forms and manifestations."
The two sides also committed to cooperate with each other by sharing information about groups and persons indulging in terrorism.
"They reiterated their commitment that their respective territories would not be allowed to be used for any activity inimical to the other," the declaration said.
On Saturday, the two countries signed historic land agreement that will allow thousands living near the border to choose their nationality following decades of stateless limbo.
A string of trade and investment agreements accompanied the land deal, with $4.5 billion of investments in power and a $2 billion credit facility, which follows a $1 billion assistance it provided in 2011 for infrastructure development, for Bangladesh also unveiled on Saturday.
Modi and his Bangladeshi counterpart Sheikh Hasina, along with the chief minister of West Bengal Mamata Banerjee, also inaugurated bus services along the border.
Among other investments, Adani Power Limited and Reliance Power Limited signed deals worth over $4.5 billion with state-run Bangladesh Power Development Board (BPDB) to develop six units of power plants to produce 4,600 MW of electricity.
Reliance will invest $3 billion to produce 3,000 MW power, while Adani will set up two coal-fired plants with a total capacity of 1,600 MW, costing more than $1.5 billion.
Prime Minister Modi returned to India on Sunday evening.
