Serbs say Nato plane shot down
Serbs say these markings belong to a F-117 Stealth fighter
Serbian television has shown pictures of wreckage which it says is a Nato warplane shot down over Yugoslavia.
The US news agency Associated Press says an unnamed senior US defence official has confirmed an F-117A Stealth fighter was missing after a mission over Yugoslavia.
But Italy's Under Secretary for Defence, Massimo Brutti, said on state television: "I have had confirmation that one plane did not return."
BBC Defence Correspondent Jonathan Marcus says although the TV pictures are not conclusive, there are aspects of the wreckage that are similar to the F-117.
"Looking at the pictures there is one particular part of the aircraft, a sort of upright strake with fingers at the end, which do look very much like an F-117," he said.
Nato broadens campaign
Reports of the downed plane came soon after Nato forces were authorised to attack a broader range of targets in Yugoslavia.
Nato spokesman Jamie Shea said the decision had been taken in the light of reports of atrocities and intimidation by Serbian forces in Kosovo.
Nato commanders may now order attacks on tanks and other military installations.
Up to now, the attacks have been aimed at Yugoslavia's air defence systems.
Nato reaffirmed it was not at war with Yugoslavia, and said President Slobodan Milosevic could halt the air raids by agreeing to international demands on Kosovo.
UK Prime Minister Tony Blair has pledged to increase Britain's air power contribution to the Nato air strikes.
Refugees crossing into Macedonia painted a consistent picture of atrocities by the Yugoslav army and the Serbian special police force, according to BBC Correspondent Clarence Mitchell.
Fourth day of attacks
A senior Nato official in Washington said strikes began on Saturday with a Tomahawk cruise missile launched onto the vicinity of the capital, Belgrade.
US officials later reported that American warships in the Adriatic had launched two Tomahawk missiles in daylight.
Air-raid sirens sounded in Belgrade and in Pristina, and large explosions were reported in the Yugoslav capital.
Witnesses reported scores of people rushing to bomb shelters after the sirens sounded and the explosions began.
Speaking on state television, President Milosevic said the Nato raids were ruining the United Nations system, and were the worst threat to peace since the World War II ended in 1945.
