JERUSALEM (AFP) - Israel and the Palestinians sharpened their rhetoric as US Secretary of State John Kerry headed to the region on Wednesday hoping to nudge the two sides towards a peace framework.
The latest United States quest for a long-elusive peace deal has shown little sign of progress since Kerry managed to revive direct talks in July, and this week leaders on both sides questioned the other's commitment to ending the decades-old conflict.
Palestinian president Mahmud Abbas warned on Tuesday that his side would take "diplomatic and legal" action against Israel in order to halt the expansion of Jewish settlements on land the Palestinians want for their future state.
"We will not remain patient as the settlement cancer spreads, especially in (annexed Arab east) Jerusalem, and we will use our right as a United Nations observer state by taking political, diplomatic and legal action to stop it," he said.
"These actions show a lack of seriousness on the Israeli side in the negotiations and threaten to destroy the two-state solution."
Israeli Prime Minister Benjamin Netanyahu had earlier slammed the Palestinians for giving a hero's welcome to 26 veteran prisoners released by Israel as part of the US-brokered talks, all of whom were convicted of killing Israeli civilians or soldiers.
"Murderers are not heroes," Mr Netanyahu said on Tuesday after Mr Abbas personally welcomed many of the prisoners at his Ramallah compound. "This is not how you educate for peace, this is not how peace is made."
"There will be peace only when our security interests and settlement interests are ensured. There will be peace only when Israel will be able to defend itself on its own in the face of any threat," he said.
Mr Kerry plans to meet with both leaders starting Thursday as he makes his 10th visit to Israel and the occupied West Bank since March.
Israel has committed to releasing 104 veteran prisoners in four batches as part of the talks, but the first two releases were accompanied by the announcement of new settlement construction, infuriating the Palestinians.
Mr Netanyahu's government was expected to make a similar move after the latest release in order to assuage hardliners within the ruling coalition.
