Prime Minister Mahinda Rajapaksa said it was shocking to see the brutal and fatal attack on Priyantha Diyawadana by extremist mobs in Pakistan.

"My heart goes out to his wife and family. Sri Lanka and her people are confident that PM Imran Khan will keep to his commitment to bring all those involved to justice," Rajapaksa said.

Meanwhile, Pakitani Prime Minister Imran Khan condemned the killing of a Sri Lankan Engineer working at a factory in Pakistan.

"The horrific vigilante attack on factory in Sialkot & the burning alive of Sri Lankan manager is a day of shame for Pakistan. I am overseeing the investigations & let there be no mistake all those responsible will be punished with full severity of the law. Arrests are in progress," Khan said.

Over 100 people have been arrested over the incident thus far.
