Last month, there were intrusions into the Indian diplomatic residential complex under construction in Islamabad.
The Pakistanis claimed the incident took place while the diplomat was returning to his home in Vasant Vihar.
In one of the latest incidents, a auto of Pakistani high commission official was intercepted by another vehicle followed by the humiliation of his pictures being taken in front of general public. The video shows a Maruti vehicle driving at a very slow speed ahead of the diplomat's auto, blocking the way.
The Pak high commission alleged that the children were harassed and blocked by Indian authorities while on way to school.
Pakistani foreign office summoned Indian Deputy High Commissioner JP Singh to the foreign office in Islamabad on Tuesday night and lodged a protest over what it called the maltreatment being meted out to the officials and families of the Pakistan High Commission in New Delhi. There was no official comment from the Ministry of External Affairs.More news: Karachi set to host Pakistan-West Indies T20Is

Pakistan on Tuesday accused India of intimidating and harassing its diplomat's children while they were on their way to school.
He emphasized that under the Vienna Convention, the safety and the security of Pakistani diplomats and their families is the responsibility of the Indian Government.
Pakistan said at least three of its diplomats, and several of their children, had been harassed in recent days. In view of such an atmosphere, many families have returned to India. "The Indian High Commission in Pakistan has been facing tremendous harassment for long, particularly in the a year ago".
"Despite repeated official protests lodged with the Indian Ministry of External Affairs at the highest level, there has been a rise in the occurrence of such disturbing events", said Dr Mohammad Faisal.
The Pakistan government has also insisted that "the membership fee and monthly charges of both clubs combined should be equal to the Islamabad Club".
Sources in India also said that on February 16, the Indian High Commissioner met the Foreign Secretary of Pakistan to lodge a strong protest against multiple acts of hooliganism against Indian properties and personnel.
