Israel has qualified for Eurovision's grand final on Saturday, hours after protesters tried to disrupt the country's dress rehearsal.
Yuval Raphael, 24, was performing New Day Will Rise during a preview show on Thursday afternoon when six people with whistles and "oversized" Palestinian flags obstructed her act. Under the arena rules, all flags are allowed but there are limits on size.
Swiss broadcaster SRG SSR, which is organising the event, said the audience members were quickly ejected from the St Jakobshalle arena.
Israel's participation in Eurovision has been a source of controversy, as its military intensifies its bombardment of Gaza, and enforces blockades of all food and other humanitarian supplies.
