Police in Kuwait cracked down Sunday on a crowd of thousands of protesters opposing the ruling monarchy’s effort to change electoral laws. The U.S.-backed Kuwaiti regime has stoked anger after dissolving parliament and proposing voting laws that opponents have described as a constitutional coup. On Sunday, an estimated crowd of up to 50,000 gathered across the capital Kuwait City in an attempt to march on government headquarters. At least 29 people were admitted to the hospital after police surrounded marchers and used tear gas and stun grenades to disperse them.
