A South Korean politician has been hospitalized after being attacked in Seoul.

Bae Hyunjin of the ruling People Power Party became the second South Korean politician to be physically attacked this month.

Party leader Han Dong-hoon told reporters that the politician was being treated at Soonchunhyang University Seoul Hospital. "This is something that should never have happened. The truth must be revealed and the guilty must be brought to justice," the leader said.

On January 2, Lee Jae-myung, the leader of South Korea's main opposition party, was stabbed in the neck while walking through a crowd of people. Lee Jae-myung was hospitalized and released from the hospital nearly eight days later.

The suspect, who said his attack was politically motivated, has been arrested and is expected to be charged with attempted murder.

In a statement on social media, main opposition leader Lee called Thursday's attack "unbelievable" and said, "No political terrorism is acceptable."

The attacks on politicians on both sides of the political spectrum just weeks apart may be indicative of the increasingly vindictive attitude in South Korean politics.
