The NATO-led Stabilisation Force (SFOR) is investigating the incident in which a group of peacekeepers "briefly detained" a resident of the northeastern town of Kalesija "suspected of video-taping an SFOR patrol," an SFOR statement said.

But Hatidza Sahbazovic accused US troops serving with the peacekeepers of severely beating her invalid husband Bajro -- who lost his leg and arm during Bosnia's 1992-1995 war -- in front of their house on Wednesday.

Sahbazovic said SFOR soldiers drove into her street while Bajro was testing an amateur video camera on his balcony.

The soldiers knocked on the door of their apartment and told their seven-year-old daughter they wanted to talk to her father but when she asked why, they left, Sahbazovic said.

"Not much later they came back and blocked our building. When Bajro went down to see what was happening soldiers jumped on him and started beating him," she said adding that her husband was hospitalised in Kalesija.

A "thorough investigation" was underway place to determine details of the incident, SFOR said.

Currently a 12,000-strong peacekeeping force is deployed in Bosnia to provide security following the 1992-1995 war.
