Hadash faction head MK Muhammad Barakei made an unapproved visit to Yemen, which is considered an enemy country, on Monday, Israel Radio reported. According to the report, Barakei, who was in the country to participate in a conference on the rights of Palestinian refugees in Iraq, did not receive the necessary authorization from defense officials before making his trip. The law requires Israeli diplomats to receive special permission from the military before visiting enemy countries. Barakei's trip was the latest in unauthorized forays by Arab MKs into enemy territory, after Balad MKs Azmi Bishara, Jamal Zahalka and Wasal Taha were questioned by the police's International and Serious Crimes Unit for their diplomatic visit to Syria and Lebanon last September.
