The US has re-affirmed its position that the Palestinian Authority is unable to join the International Criminal Court as it is not a sovereign nation.
Reuters report that President Barack Obama spoke by phone on Monday with Israeli Prime Minister Benjamin Netanyahu about ongoing nuclear talks with Iran and about the Palestinian move to become a member of the International Criminal Court, the White House said.
"President Obama underscored that the United States does not believe Palestinian accession to the ICC is a constructive way forward," a White House spokesperson said, repeating the US position that the Palestinian Authority is not a sovereign state and does not qualify to join the court.
Arab League foreign ministers agreed on to formally present a draft resolution to the United Nations Security Council that will set a timeframe for the creation of a Palestinian state.
The Swiss investigators who detected enough polonium in the body of Yasser Arafat to kill him say there should be an inquiry into how the former Palestinian leader died.
Many Palestinians agree, but Israel has dismissed the idea as a conspiracy theory.
ITV News Middle East Correspondent Geraint Vincent reports.
An expert in radioactivity measurements told ITV News that while he believes the scientists who concluded Arafat was poisoned did a "thorough and careful job" and considered factors that could impact their findings, the seven-year delay makes the statistical certainty of their conclusions "limited".
Hanan Ashrawi, who was close to Yasser Arafat and saw him shortly before he left for Paris has said that his illness looked "unnatural."
She said: "I talked to the medical teams that were examining him, they told me that unquestionably that he was poisoned, but they couldn't identify the poison."
Ms Ashrawi said that "we have to pursue now the people that are responsible justice has to be done."
The widow of Yasser Arafat, Suha, has described how weak the former Palestinian leader was before his death after it was revealed that scientists have found a high level of polonium 210 in his exhumed body.
Mrs Arafat said: "Words can't express my deep sorrow and the sorrow of my daughter, but mostly the anger - we are so angry. It's a political crime, a political assassination. It is so hard, we are mourning him again."

The Israeli government has denied any role in the death of Yasser Arafat, saying that he was 75-years-old.
"This is more soap opera than science, it is the latest episode in the soap in which Suha opposes Arafat's successors," Israeli Foreign Ministry spokesman Yigal Palmor said.
The investigation amounted to "a highly superficial attempt to determine a cause of death".
Suha Arafat, the widow of the late Palestinian leader said: "When they came with the results, I’m mourning Yasser again. It’s like you just told me he died. I will not stop. Me and my daughter will go to all courts in all over the world to punish who did this crime."
Some experts have questioned whether Arafat could have died of polonium poisoning, pointing to a brief recovery during his illness which is not consistent with radioactive exposure. They also noted he did not lose all of his hair.
But Professor David Barclay said neither fact was inconsistent with the findings.
Since polonium loses 50% of its radioactivity every four months, the traces in Arafat's corpse would have faded so far as to have become untraceable if the tests had been conducted a couple of years later, Professor Barclay said.
