A Kuwaiti court sentenced two men accused of spying for Iran and Lebanon's Hezbollah to death on Tuesday. The case also included the possession of weapons. One of the men given the death penalty was an Iranian convicted in absentia and the other was a Kuwaiti who was in court, Reuters reported. Other suspects were given sentences ranging from five to 25 years and three were found innocent. Tensions between Iran and some Persian Gulf Arab states have escalated since a diplomatic dispute between Tehran and Riyadh erupted after Riyadh's execution of prominent Shia cleric Sheikh Nimr al-Nimr this month. Saudi Arabia broke off relations with Tehran after its diplomatic missions were stormed by Iranian protesters in Iran, while Kuwait recalled its envoy to Iran.
