Palestinian leader calls on US to mediate hunger strike

Palestinian President Mahmoud Abbas has asked the United States to help end a weeks-long hunger strike by Palestinians held in Israeli jails, as the Red Cross warned the strikers were entering a "critical phase".

Hundreds of the prisoners have been refusing food since April 17 over conditions for about 6,500 Palestinian inmates.

Speaking to senior members of his Fatah party in Ramallah after meeting President Donald Trump's special representative Jason Greenblatt, Abbas said he had spelt out his position to the envoy who would convey it to the Israelis.

"We have explained in detail to American envoy Jason Greenblatt the issue of the prisoner strike and we have called for American intervention to ensure that the rights of prisoners are protected and their humanitarian demands are granted," he said.

"We shall be in touch with him to give us the answer of the Israeli side," he said, adding he hoped to announce a response "in the evening or tomorrow".

Greenblatt is in Israel and the Palestinian territories to follow up on Trump's visit earlier in the week and to build on his plans for a new Israeli-Palestinian peace initiative, according to Israeli media.

The hunger strike is being led by prominent Fatah figure Marwan Barghouti, who is serving five life sentences for murders committed during the second Palestinian intifada, or uprising.

Among the strikers' demands are access to telephones, more family visits, improved medical care and an end to punitive solitary confinement.

The International Committee of the Red Cross said Thursday that its doctors who have been visiting the prisoners were concerned about "potential irreversible health consequences".

"From a medical standpoint, we are entering a critical phase," it added, urging the authorities on both sides to find a solution to the standoff.
