Nigerian President Goodluck Jonathan and labour unions met late Sunday but failed to reach a compromise over the removal of fuel subsidies that has raised fears of a shutdown of Nigeria's oil industry, presidency sources said.
Jonathan was expected to make a public address following the talks and unions refused to give comment until he had spoken, but several sources said no agreement had been reached. The president's address may now be aired later Monday.
Unions said Sunday that nationwide strikes and protests would resume Monday if no agreement was reached.
Tens of thousands took to the streets for strikes over five successive days last week in protest against the sudden removal of a fuel subsidy on January 1 that more than doubled the pump price of petrol to 150 naira ($0.93) per litre from 65 naira.
