Nigerian doctors today began a 5-day warning strike following a 21-day ultimatum issued weeks ago to the federal government, demanding pay rise, improved welfare, infrastructure and other benefits which was promised to them.

The President of the Nigerian Medical Association, Dr Osahon Enabulele said this is the first phase of the strike, that the second phase would be effective after the yuletide if there are no favorable developments.

All doctors in public hospitals this morning retrieved their services.
