DUBAI — Bahrain has arrested several people in connection with Tuesday's deadly bombing and suspect the attack was a “foreign attempt” to harm the Gulf state's stability, local media reported on Wednesday. A published comment by Prime Minister Sheikh Khalifa Bin Salman alleging a foreign role did not name any country, but Bahrain has frequently accused regional adversary Iran of trying to orchestrate bombings in the country. Tehran dismissed suggestions it had a role in the attack. “Terrorism and extremism are the main challenges facing the region,” Foreign Ministry spokeswoman Marzieh Afkham was quoted as saying by Iran's Press TV on its website. Sheikh Khalifa said Bahrainis' patriotism had “always foiled foreign attempts to interfere in the kingdom's internal affairs”, the official Bahrain news agency reported. “The prime minister reiterated categorical rejection of foreign interference, expressing deep regret over the martyrdom of two police officers,” he was quoted as saying. The bombing in Sitra was the deadliest in the kingdom since March 2014, when a blast killed three policemen. It drew strong condemnations from fellow Gulf states who share Bahrain's suspicion that Iran is seeking to foment instability in Arab lands. — Reuters
