Nato said on Tuesday it was unaware of embattled Libyan leader Muammar Gaddafi being dead or alive and denied its air strikes on Tripoli were aimed to kill him.
"All Nato targets are military targets, which means that the targets we've been hitting are command and control bunkers," Nato spokesman Claudio Gabellini told reporters, adding "and it happened also last night in Tripoli".
"Nato is not targeting individuals," he said via videolink from the operation's headquarters in Naples, Italy.
When asked whether Gaddafi was still still alive, the Italian Nato general said, "We don't have any evidence. We don't know what Gaddafi is doing right now."
Fresh sorties by Nato warplanes struck the Libyan capital on late Monday and on early Tuesday in some of the heaviest bombing missions in weeks. The air strikes reportedly targeted a military base and a compound used by Gaddafi.
Nato earlier rejected claims by Libya on Tuesday that the military alliance attacked the Supreme Court building in Tripoli and various civilian targets.
Since the Nato mission in Libya began March 31, its jets have conducted a total of 5,968 sorties, including more than 2,300 strike missions, the alliance said on Tuesday.
