Markets, public transports, education institutions and other businesses remained closed here and other places in the valley.

Chief Electoral Officer (CEO) Shant Manu on Sunday said re-poll would be held at 50 to 100 polling stations where violence had resulted in the disruption of polling process.  

Around seven per cent votes were polled during Sunday's by-poll which marked the lowest voter turnout in the last 27 years.

The CEO has said that the next phase of the by-poll would be held on schedule on April 12 in south Kashmir's Anantnag parliamentary constituency.

Meanwhile, to check the spread of rumours by anti-social elements authorities have decided to suspend the internet facility in the entire valley till April 12.
