Support for a two-state solution among Israelis has plummeted 11 per cent in the past year, according to a new poll.
The research also identified a drop in support among Palestinians, from 54 per cent to 51 per cent. Israeli support for the two-state solution also stands at 51 per cent following the drop.
"There's a perception on both sides that it's becoming less and less practical," said Khalil Shikaki, of the Palestinian Centre for Policy and Survey Research, who directed the polling together with Hebrew University academic Ifat Maoz.
He said that the Israeli drop had been fast and sudden, while the Palestinian fall follows an ongoing pattern. Palestinians are frustrated at the lack of progress towards fully-fledged statehood, he said, whereas Israelis fear ceding territory while groups such as Isis threaten the country's borders.
He added that on both sides there is a growing feeling that settlements are deeply entrenched and that it is hard to imagine them being dismantled.
