Kenyan teachers have called off a strike for higher pay that started on September 3 after signing a deal with the government, their union said on Monday.

The highest paid will get 142,000 shillings a month, a rise of 22,000 shillings. Unions had demanded between 100 and 300 percent pay rises.

"If everything else fails, the last resort is we increase tax," he told Reuters, adding he expected concrete proposals by the end of this week. The pay rises will be back-dated to Jul
