MOSCOW, July 1 (RIA Novosti) - The Palestinian Authority has information indicating Hamas is planning to kill some of its officials, the Palestinian president said on Wednesday.

In an interview with satellite TV channel Russia Today, Mahmoud Abbas said there were people "who are stockpiling arms, ammunition and explosives."

"Hamas is preparing a terrorist attack. Furthermore, we have learned that there is a group that is preparing to kill certain people," he said.

He added that Palestinian enforcement officers had discovered two tons of explosives, small arms, grenade launchers, and machine guns in a residential area.

"We're watching them and we will get them," Abbas said.

The Hamas and Fatah movements, the largest Palestinian political organizations, split in June 2007 when Hamas took control of the Gaza Strip and pushed the Fatah movement out of the enclave of 1.5 million. Hamas has since remained in power in Gaza, independent of the officially recognized government of Fatah in the West Bank, which is headed by Abbas.
