COLOMBO: Sri Lanka has expelled over 600 foreign nationals, including around 200 Islamic clerics, since the Easter suicide bombings blamed on a local jihadi group, a minister told AFP Sunday. Home Affairs Minister Vajira Abeywardena said the clerics had entered the country legally, but amid a security crackdown after the attacks were found to have overstayed their visas, for which fines were imposed and they were expelled from the island.
