LIMA (AFP) - Air traffic controllers in Peru launched a three day strike on Wednesday to press for salary hikes, causing delays to domestic and international flights.

More than 1,000 unionized controllers are also seeking better working conditions.

Union leader Cesar Palacios said the strike was enjoying widespread support among controllers themselves and administrative staff.

Strikers staged a sit-in outside Lima airport on Wednesday to press their case.

Delays were reported in domestic and international flights.

The government is bringing in military air traffic controllers to ease the effects of the stoppage, said Luis Rivera, manager of the civil aviation agency, called Corpac.
