TRIPOLI, Libya — NATO acknowledged Saturday that its aircraft had mistakenly hit a column of rebel military vehicles last week near the Libyan oil port of Brega, and early Sunday morning the Qaddafi government showed reporters a destroyed cinder-block house that neighbors and the government said was hit by an errant NATO airstrike in the capital.

Two bodies were pulled from the rubble, and at the Tripoli Central Hospital, government officials showed reporters three others, including an infant and a child, who they said were killed in the house.

It was the first time in three months of airstrikes that the Qaddafi government has presented credible evidence of what appeared to be direct civilian casualties of NATO attacks. Although the government has often claimed large numbers of civilian deaths, it has never previously presented bodies or consistent facts about the dead.
