Jerusalem (CNN) Hundreds of Palestinian prisoners in Israeli jails ended their hunger strike Saturday after 40 days, officials said.

The hunger strike ended hours before Ramadan following a marathon 20-hour negotiating session, said Issa Qaraqe, head of the Prisoners' Affairs Committee and Qadura Fares, who leads the Palestinian Prisoners' Club.

The Israel Prison Service also confirmed the end of the strike.

Nearly 1,600 prisoners began the strike on April 17, which is known as Palestinian Prisoners' Day.
