The Road Freight Employers' Association says negotiations with striking truckers in South Africa ended without a settlement Tuesday and that no further meetings are scheduled.

The RFEA accused the striking truckers of shifting goals during wage negotiations, saying it could not "responsibly consider" their demands any longer.

The association said early on Tuesday that it had reached a deal with three of the four unions it is negotiating with, only to announce later that no deal had been reached.

A spokesman for the influential South African Transport and Allied Workers' Union, or SATAWU, accused the RFEA of walking out of talks.

The union, which is demanding a 12 percent pay raise for its 28,000 members, has threatened to intensify the strike by inviting rail and port workers.
