"Mobile phone and portable Internet services were shut down from 9 AM till noon to ensure that no electronically controlled remote control devices were operated by militants," an official said.

These services remain shut on Republic Day and Independence Day after militants used a mobile phone to trigger a bomb blast outside Bakshi Stadium in 2005.

Meanwhile, despite chilling conditions and overnight snowfall, thousands of people across Kashmir thronged the venues where Republic Day were being celebrated.

The main function in the Valley was held at Bakshi Stadium here amidst tight security.

JK Finance Minister Abdul Rahim Rather unfurled the national flag at Bakshi Stadium where over 5,000 people attended the function.

Opposition PDP chief Mehbooba Mufti, Minister of State for Home Nasir Aslam Wani and ruling NC MLAs Peer Afaq and Irfan Ahmad Shah were also present at the venue.

Contingents of police, CRPF, BSF and students from various schools participated in the Republic Day parade as Rather took salute.

Large number of people had turned to witness the parade despite chilling weather, as mercury was sub-zero at the time of the event, and light snowfall overnight.

Reports of good turnout of people at Republic Day functions were received from almost all district and town headquarters in the Valley.

Bandipora witnessed the highest attendance of 14,000 people attending the Republic Day function as CAPD Minister Qamar Ali Akhoon unfurled the tricolor.

Education Minister Peerzada Mohammad Sayeed hoisted the National Flag at Baramulla district headquarters where over 10,000 people attended the function.
