Quetta Politicians in the Pakistani occupied province of Balochistan have sought U.N. help against security forces' action in the region.
In a letter to the U.N. Secretary-General Kofi Annan, they said Pakistan was determined to build three more military cantonments in Balochistan to suppress the Baloch voice.
They said more than 600 military checkpoints had been established throughout Balochistan to control the movement of the Balochi people.
"There are 60,000 troops stationed in Balochistan and more are on their way," the politicians said.
Pakistan's army has launched an offensive against Baloch rebels, who have been waging an armed struggle against the forces demanding a greater share of the region's income. Pakistan says the tribal region has become a haven for militants.
"Pakistan air force fighters, army gunship helicopters and heavy artillery is being used against unarmed innocents and nomads of these areas," said 13 members of the Balochistan Provincial Assembly in a signed letter.
They said the construction of army cantonments and large-scale deployment of security forces all over Balochistan present a picture of siege and have created a sense of insecurity among local tribes.
"There are four mega military cantonments, 52 paramilitary cantonments, five naval bases including Jinnah naval base in Gwadar and six major air force bases," they said.
The legislators said there are also three nuclear testing sites and six missile testing ranges in Balochistan.
The politicians have appealed to human rights bodies and Amnesty International to intervene.
