Amman - Four Jordanian Islamists have been arrested for allegedly planning attacks on Israel in retaliation for the "massacres" it committed during its 22-day offensive on the Gaza Strip in January, judicial sources said Wednesday.

More than 1,300 Palestinians were killed and about 4,000 wounded in the Gaza attack.

The four people, who were detained in April, are expected to be charged with the possession of arms without license for illegal uses, the sources said.

The suspects were identified as Sakhr Abu Zaid, Hassan Talaq, Mohammad Abu Ourah and Osama Abu Kabir. The last-named was a Guantanamo prison detainee for several years, they added.

Under the peace treaty which Jordan concluded with Israel in 1994, the Hashemite Kingdom committed itself not to allow attacks on the Jewish state from Jordanian territory. (dpa)
