Thousands of passengers were stranded or greatly delayed overnight and on Monday at Kenya's biggest international airport as workers' slow-down strike continued into its second day.

The strike at Nairobi's Jomo Kenyatta Airport by Kenya Aviation Workers' Union (KAWU) is the latest in a series over poor working conditions and the lack of a collective bargaining agreement with the country's Civil Aviation Authority.

KAWU has also accused the Kenya Airports Authority (KAA) of a lack of support for workers, and voiced its disapproval of a plan to use youth volunteers as airport staff.

Union leader Moss Ndiema said that KAWU had met with government officials on Sunday to try and resolve the dispute, but were unsuccessful in coming to an agreement.
