"Total normalcy" prevails in Occupied Kashmir, India's home minister said Wednesday even as the government said 600 people remained in custody since the region, cut off from the internet, was stripped of its autonomy in August.

"Petrol, diesel, kerosene, LPG (liquid petroleum gas) and rice are adequately available," Amit Shah, Prime Minister Narendra Modi's right-hand-man, told India's upper house the Rajya Sabha in New Delhi.

"The situation there was always normal. There were many notions spread all over the world. There is total normalcy prevailing," Shah said.

On August 5, Modi's Hindu nationalist government moved to revoke the occupied state's special status, sending in tens of thousands of extra troops, imposing a curfew, snapping telecommunications and arresting several thousand people.

Hundreds of people are known to remain in custody three and a half months later, among them dozens of local politicians including three former chief ministers of Occupied Kashmir, some of them in locations around India and many without charge.

G. Kishan Reddy, minister of state in the Ministry of Home Affairs, on Wednesday put the number of arrests since August 4 at over 5,000 and the number of people still under detention at 609.

Those arrested included "stone pelters, miscreants, OGWs, separatists and political workers," he said, referring to "overground workers" or people helping anti-India militants.

Landlines have been restored, as have postpaid mobile phones. But prepaid mobile phones and the internet remain cut off for the occupied Kashmir Valley's more than seven million people.

Shah said on Wednesday that it was up to the authorities to decide when to restore internet connections.

"There are activities by Pakistan too in Kashmir region, so keeping security in mind, whenever the local authority deems it fit, a decision will be taken [on resuming internet services]," Indian media quoted him as saying.
