Kuwait will deport 15 Egyptians who took part in an illegal rally in support of Egyptian presidential candidate Abdel Fattah al-Sisi, a Kuwaiti government source said. Kuwaiti authorities are especially wary of political gatherings that could stir tensions in the Gulf Arab state, where expatriates make up around two-thirds of the 3.8 million population. They were seen beating drums and waving, the report said, and planned to join other Egyptians to express their support for Sisi before they were arrested by police. Egypt's presidential election is being held on May 26-27 and overseas voters have already started going to the polls.
