ISLAMABAD, JANUARY 2 Reacting strongly to India’s remarks on the spiralling violence in Balochistan, Pakistan today said it ‘‘betrayed the psyche of a bully’’ and tended to vitiate the atmosphere created by the two sides for sustaining the composite dialogue process.

‘‘Anyone who says that there is nothing extraordinary about a statement that tantamount to interference in the internal affairs of other countries betrays the psyche of a bully, a bully who sees a red rag everywhere. Our advise to the Indian officials would be to mind their own business,’’ said Foreign Office spokesperson Tasnim Aslam.

She was replying to a question about a comment by an Indian official that there was nothing extraordinary about India expressing concern in developments in Balochistan. Aslam said statements from India expressing concern over Pakistan armed forces’ action against Baloch rebels ‘‘tend to vitiate the atmosphere which we have worked so hard to build for sustaining the bilateral composite dialogue process to find peaceful and just solution to the Kashmir dispute and other disputes between out two countries.’’

Meanwhile four people have been killed in a bomb blast in Balochistan as fighting erupted in the restive province where para-military troops conducted operations against rebels opposed to the construction of Army cantonments.

Four persons were killed and one tribesman injured in a bomb explosion in the Mashkal area of Kharan district, officials in provincial capital Quetta told Dawn daily.

The exchange of rocket fire occured yesterday between the security forces and Baloch nationalists who are opposed to construction of Army cantonments and are demanding more autonomy for the province.

The Baloch Nationalist Jamhoori Watan Party, Secretary General Agha Shahid Hasan Bugti accused security forces of attacking tribesmen without any provocation in Sungsila corner in south-west Balochistan yesterday.
