Pakistan today summoned the Swiss Ambassador to lodge protest over the display of anti-Pakistan posters in Geneva, Radio Pakistan reported. Ambassador Thomas Kolly was summoned by the Foreign Office in the wake of some posters, which read "Free Balochistan", emerging in Geneva. The poster campaign was apparently orchestrated by the Balochistan Liberation Army (BLA), a banned entity in Pakistan. Officials said the Switzerland government has been urged to take action against moves which are against the sovereignty of Pakistan. Earlier, the Pakistan's Permanent Mission to the United Nations in Geneva demanded that the government of Switzerland take strict actions against those involved in the act. In his letter, the Permanent Representative of the Mission, Farrukh Amil, said the use of Swiss soil by terrorist and violent secessionists for nefarious designs against Pakistan and its 200 million people is totally unacceptable. He said terrorists or elements linked with terrorists operating openly in the peaceful and serene city of Geneva for their propaganda campaigns is a matter of grave concern. The Ambassador added that Swiss authorities should be alert about presence of BLA terrorists, or elements linked with them, in Geneva. Amil also demanded an investigation into the campaign with a view to blocking its recurrence and expressed hope that Swiss authorities will proceed against the local accomplices of the BLA for supporting a terror group.
