Sri Lanka's government has accused Tamil Tiger rebels of killing an army intelligence officer and a civilian in the country's volatile east.
A government spokesman says Thursday's killings in the town of Polonnaruwa had all the "hallmarks" of a Tamil Tiger attack. Sri Lanka said the incident also casts doubts on the rebel group's commitment to a Norwegian-brokered cease-fire signed in 2002.
No one has claimed responsibility for the ambush.
The Tamil Tigers have waged a 20-year campaign for greater autonomy for Sri Lanka's ethnic Tamil minority. The conflict claimed more than 60,000 lives before the cease-fire went into effect. Subsequent peace talks collapsed in April 2003.
