This isn’t the first time that the safety of the U.S. ambassador has been put at risk with protesters scaling the walls to get inside:
The government requested Friday that law enforcement authorities beef up security around the US Embassy and the residence of the top American diplomat in Seoul after nearly 20 university students trespassed in his residence.
Earlier in the day, 17 students and members of a progressive civic group broke into the residence of US Ambassador Harry Harris in central Seoul by climbing over its wall using a ladder.
They staged a surprise protest criticizing Washington’s demand for a hefty rise in Seoul’s share of the cost for the upkeep of the 28,500-strong US Forces Korea. Police took the 17 and two others attempting to join them into custody for investigation.
