Hundreds of thousands protest in Northern Ireland

Tens of thousands of public sector workers in Northern Ireland have walked off the job, in what one union leader said could turn out to be the biggest strike in the country, AFP reported.
The mass strike, dubbed a "coordinated day of action", is expected to wreak havoc on already battered public services.
The strikes come with no end in sight to a protracted political crisis that has left the British province without an autonomous government for nearly two years.
About 16 unions representing teachers, civil servants, nurses and transport workers were expected to join the protests and rallies, according to organizers.
Six rallies were planned to take place in Belfast, two more in Londonderry, also known as Derry, and one in Enniskillen.
Union boss Owen Reidy said the "biggest industrial dispute in Northern Ireland's history" was expected.
"Public service workers in Northern Ireland have been used as political pawns by this discredited Tory government," said Reidy, who is general secretary of the Irish Congress of Trade Unions (ICTU).
"Many of these workers have not received a pay rise for 3 years despite the cost of living crisis. The money is available but the workers are being held captive."
According to ICTU estimates, 170,000 of the 220,000 unionized public sector workers will stop work to demand the release of withheld pay rises.
The Department of Health warned there would be "significantly reduced health services" and advised people to aim to "reduce their chances of needing treatment in the health service".
Authorities said health services would be severely limited, although basic and emergency care would remain available.
Schools are closed and transport services are suspended as several hundred workers from services that salt roads during the winter go on strike to coincide with the cold weather.
The strike, which is estimated to cost the economy more than £10m, comes as the region's political stalemate approaches two years. /BGNES
