Palestinian leader Mahmoud Abbas has told official media to avoid broadcasting material Israel could view as incitement against it, a senior official said on Monday about a move demanded by Ariel Sharon. Radwan Abu Ayyash, head of the Palestinian Broadcasting Corporation, said Abbas issued the instructions last week when he met PBC officials and told them to review programmes before they are aired. "He said that he prefers self-censorship of the broadcast material to ensure that programmes do not include material that might be interpreted (by Israel) as so-called incitement," Ayyash said. "We already started watching out for anti-Israeli incitement in our programmes and our news bulletins. As of now, we have not found anything that could be seen as inciting," Ayyash said. Since an uprising began in 2000, Palestinian media have constantly aired nationalist songs, funerals of Palestinians killed by Israeli troops - the men and women are described as "martyrs" - and the demolition of homes by the Israeli army. "The ball is in the Israeli court. If they stop killing, television will stop showing these pictures," a Palestinian official said.
