South Korea will send $500,000 in humanitarian aid to Yemen as it struggles with a civil war, Seoul's foreign ministry said Tuesday.

South Korea will deliver the aid through the United Nations, the International Organization for Migration and the International Committee of the Red Cross, it said.

The chaos in Yemen comes as Saudi Arabia and a coalition of Gulf Arab nations have launched air strikes against Shiite rebels, known as Houthis, after they ousted Yemen's government and dissolved the parliament in early February.

More than 600 civilians have died and nearly 2,200 others have been injured since the attacks began, according to an estimate of the World Health Organization.

The U.N. has also said that 25 million people in Yemen require humanitarian aid. (Yonhap)
