Seoul: South Korea Thursday urged its citizens to leave Yemen as dozens of people protested against two suicide bombings which killed four of their compatriots.
Seoul issued the warning after a suicide bomber on Wednesday attacked a South Korean delegation, just days after the deadly weekend bombing at a historic tourist site which was blamed on Al Qaida.
Yemen authorities have offered a cash reward for information leading to the arrest of 12 men it said were preparing new attacks.
About 100 activists protested outside the foreign ministry, chanting slogans and waving banners including one reading "Crush Al Qaida terrorists."
No one was hurt in Wednesday's blast.
