In a faxed message, both to Indian High Commission in Islamabad and to Ministry of External Affairs here, the Pakistan Foreign Office has expressed concern over the incident.
"Concerns on organised demonstrations against Pak High commission & mobbing of Pakistan-bound bus conveyed to Indian authorities," the Pakistan High Commission tweeted.
It added that Pakistan was also concerned over reports carried by Indian media about "communal violence on Eid in Jammu & incarceration of Hurriyat leaders".
Around 100 protesters, headed by their state unit president Vikram Chowdhary, stopped the bus which was carrying 30 passengers for around half-an-hour and demanded immediate stoppage of the bus service to the neighbouring country.
