Bassam al-Safadi, a journalist for the Al-Alam news channel, was arrested Wednesday on suspicion of "supporting a terrorist organisation and incitement to violence and terrorism," police said.
A court in Nazareth in northern Israel extended his remand until Sunday, when he was released "under limitations, including a five-day house arrest," police said.
In an interview with Beirut-based Al-Alam on Sunday, Safadi said he was "accused of incitement to terrorism, supporting terror organisations and standing behind terror organisations."
The 43-year-old was described by police as Arab Israeli, but many Arab residents of the Golan, who are from the Druze community, consider themselves Syrians.
Hussein Mortada, head of Al-Alam's office in Syria, said on Wednesday that the arrest was part of a "systematic campaign" by Israel against the media.
Israel seized 1,200 square kilometres (460 square miles) of the Golan Heights from Syria in the 1967 Six-Day War and later annexed it in a move never recognised by the international community.
