NEW DELHI, Jan. 7 (Xinhua) -- India could face serious power shortage in the coming days as a five-day strike by coal industry workers nationwide entered the second day on Wednesday, said local media reports.

Negotiations between government officials and trade unions failed late Tuesday night as the unions blamed the government for failing to bring any proposal to solve the crisis.

On its first day, the strike impacted 75 percent of the 1.5 million tons of daily coal production, while fuel supplies to nearly 100 power plants across the country may also be affected if the impasse continues, according to local daily The Hindu.

Unions said nearly 500,000 workers, including those of Coal India, have joined the strike aimed at seeking better pays and working conditions.
