JERUSALEM, Israel -- Egyptian President Mohammed Morsi called his Sudanese counterpart Thursday to condemn Tuesday's airstrike on a weapons factory in Khartoum, which is being blamed on Israel.

Morsi told President Omar al-Bashir he condemned "Israeli aggression against Sudan."

Israel has neither admitted nor denied the attack, which destroyed half the weapons facility and heavily damaged the other half. Two people were killed, Sudanese sources said.

An unnamed diplomatic source told AFP the munitions factory was also producing drones.

"There was supposed to be an agreement between Sudan and Iran to produce some kind of nonconventional weapons," the diplomat said.

Sudan has long been suspected of funneling Iranian arms to Hamas terrorists in Gaza.

Khaled Meshaal, who recently said he's stepping down from Hamas leadership, telephoned Al-Bashir to condemn the "barbarian attack."

Sudan also blamed Israel for a drone that targeted a convoy south of the Sudanese capital in September, reportedly destroying some 200 tons of munitions, including rockets, meant for Hamas.

Sudanese Information Minister Ahmed Belal Osman told reporters "four military planes attacked the Yarmouk plant."

Vice President Ali Osman Taha said Sudan reserves the right to retaliate against Israel.

"We believe Israel is behind it," he said. "Israel is a country of injustice that needs to be deterred."
