He also lashed out at the Akalis for indulging in "street politics" at the cost of public welfare.
The chief minister's reaction came a day after the Akali Dal led by Sukhbir Singh Badal blocked roads and national highways in protest against alleged attacks on its party workers and registration of "false" cases against them.
Amarinder said his government would not allow a law and order breakdown in the state, nor would it permit anyone to hold the citizens to ransom.
"Military convoys could not move in time and essential supplies could not reach the soldiers standing guard at the borders due to this ill-thought and abhorrent decision of the Akalis," he said.

Rejecting the Akalis' claim of mobilising masses, the senior Congress leader said they were indulging in "street politics" out of "sheer desperation", hoping it would help them recover some of the lost political ground.
