Amman - The Jordanian authorities on Wednesday freed four prisoners who were transferred last year from Israel to spend the remainder of their jail term at Jordanian prisons, an official statement said.

The four Jordanians - Sultan Ajlouni, Salem Abu Ghalyoun, Khalid Abu Ghalyoun and Amin al-Sane - were released after ending three quarters of their remaining jail term at Jordanian jails, the spokesman for the Public Security Department Major Mohammad Khatib said.

"The Justice Ministry has already informed the Israeli authorities that the remaining jail term of the four Jordanian citizens will be calculated according to the valid Jordanian legislations," which allowed their release after spending three quarters of their remaining imprisonment term, he added.

The four men were handed over by Israel to Jordan in July last year as a gesture of goodwill.

Under the agreement reached by the two sides, the Jordanian authorities had the choice of freeing them within 18 months or if Israel released Arab prisoners jailed for similar charges.

The four prisoners were serving life imprisonment after Israeli courts found them guilty of killing two Israeli soldiers in 1991.

The Jordanian government has come under mounting public pressure to free the four prisoners, particularly after the prisoners swap deal which went into effect last month between Israel and Lebanon's Hezbollah militias. (dpa)
