DUBLIN, Ireland (AP) _ Police sealed off parts of central Dublin on Sunday to allow army troops to clear trash that piled up for 13 days due to a strike by garbage collectors.

The force moved in early in the morning, taking the strikers by surprise and meeting little resistance. An attempt Friday by police and troops to remove trash resulted in a bloody clash with picketing garbagemen.

Twenty truckloads of troops spent almost four hours clearing hundreds of tons of refuse from an open-air market off O'Connell Street, one of Dublin's main business areas.

The 4,500 municipal sanitation and waterworks attendants rejected an offer of a 7 percent pay increase phased over 18 months. The offer would have increased their average earnings from $200 a week to $215.
