run Kuwait Airways cancelled more flights Sunday as a strike by workers calling for better pay went into a second day, in the latest round of industrial action to hit the country. The carrier was forced to cancel seven flights Sunday, spokesman Adel Boursli told state-run agency KUNA. It cut nine flights Saturday after employees started their walkout. The government announced a 25 percent rise in pay for state workers last week but several unions have said the measures did not go far enough. Around 3,000 customs workers also went on strike at Kuwait's borders and ports last week with similar demands for higher pay. The airline's 4,000 unionized workers last walked out in October and were able to secure a 30 percent pay rise, according to figures quoted in local media.
