Iran condemned Kuwait on Tuesday for sentencing two Iranians, a Kuwaiti and a stateless man to life in prison for spying for Iran and demanded they be released.

On Monday, Kuwait's appeals court reduced a death sentence on the two Iranians and the Kuwaiti to life and upheld the stateless man's sentence.

Kuwait's appeals court on Monday reduced a death sentence on two Iranians and a Kuwaiti to life in prison and upheld a life term on a stateless man on charges of spying for Iran, a judiciary source said.

Arab League foreign ministers are to hold an emergency meeting on a massacre in Syria in which U.N. observers say government forces killed 92 people, the bloc's current president Kuwait said on Sunday.

"Kuwait will contact members of the Arab League to hold an emergency ministerial meeting to study the situation and take measures to put an end to the oppressive practices against the Syrian people," said a foreign ministry statement cited by the official KUNA news agency.

Hundreds of Kuwaitis including several MPs rallied outside the Syrian embassy on Saturday to condemn a reported massacre in the Syrian town of Houla and to demand the arming of the rebel Free Syrian Army.

President Michel Suleiman on Wednesday said that a letter sent to United Nations chief Ban Ki-moon by Syria’s envoy to the U.N. Bashar al-Jaafari was not based on “verified facts.”

Kuwait's cabinet on Wednesday boycotted parliament for a second day as MPs accused the government of plotting to dissolve the opposition-controlled house.
