Delhi, April 26
The diplomatic war between Delhi and Rawalpindi is intensifying. India has told the Pakistan High Commission staff here not to leave the country without the Government's permission. The commission has also been asked to give one month's notice of a courier's intention to travel from India to Pakistan.

It is understood that these restrictions are the result of Pakistan's reported instruction to all checkpoints and airports not to allow Indian diplomats to leave Pakistan.

The Pakistan High Commissioner here called at the Foreign Office before 6 a.m. G.M.T., well within the deadline that Delhi had set for a categorical assurance to be received from Rawalpindi that Indian diplomatic staff at Dacca would be returned safely.

The High Commissioner gave assurances about security arrangements for the diplomats.

An Indian Government spokesman explained that it had been necessary to fix a deadline because of Pakistan's "failure" to give assurances about the repatriation of diplomatic staff.

A Note which Pakistan sent to India said that "safe conduct of Indian personnel and security of their premises, records and archives in Dacca will be provided strictly on the principle, of reciprocity ".

India protested to Pakistan today about what it called the "uncivilized and condemnable behaviour" of Pakistan authorities towards the wife of India's Deputy High Commissioner in Dacca, and other Indians travelling between India and Pakistan ".

The External Affairs Ministry has demanded that the culprits responsible for these "outrages" should be punished.
