A strike prompted by a labour dispute grounded flights at Kenya’s main international airport in Nairobi early on Wednesday, reports has it that Kenya Airways flights were already disrupted.

The strike at the Jomo Kenyatta International Airport follows a labour dispute between the Kenya Aviation Workers Union and the airline.

Hundreds of passengers were left to wait outside the domestic terminal and riot police were dispersed picketing ground staff, adding that three planes took off at about 8:30 a.m. despite the strike.

Due to the ongoing strike, Kenya Airways have announced via its twitter page that customers on flights after 11 a.m. should not come to the airport until further communication is shared.

Leader of the union, Moss Ndiema was arrested shortly after making a speech at the airport, media said. A court injunction had earlier ordered the suspension of the planned industrial action.
