 General Pande Petrovski prepared the plan of the offensive named "Operation Polog", but President Trajkovski refused to sign it.According to Petrovski, Trajkovski was constantly being assured by NATO and US envoys that the NLA would retreat peacefully from the area once the political dialog with the Albanian political parties intensified.At the beginning of August 2001, Macedonian Intelligence Service received information that a special unit of the NLA had infiltrated the suburb of Cair in Skopje.
