Pakistan's Embassy in Tehran and its Consulate in Zahidan are in constant touch with the Iranian authorities for a comprehensive investigation to ensure that perpetrators, involved in the killing of innocent Pakistanis, are brought to justice.

The Foreign Office Spokesperson, in a statement on Sunday, also urged the Iranian authorities to ensure prompt repatriation of the victims' remains to Pakistan.
