Between 10 and 15 gunmen opened fire at an upscale shopping mall in Nairobi, Kenya, on Saturday, killing at least 68 people and injuring over 1-hundred-70.
The shooting started around noon, local time, at the Westgate shopping mall in the capital.
Eyewitnesses said the gunmen threw grenades and fired indiscriminately at shoppers.
"We tried escaping. And they threw a grenade, the sharp particles entered my hands and my legs. There were many people injured."
A Korean citizen is among the dead.
Seoul's Foreign Ministry says 38-year-old Kang Moon-hee died from gunshot wounds.
Officials say Kang had moved to Kenya with her British husband, who is currently recovering at a nearby hospital.
Another Korean citizen who was initially reported missing has been confirmed safe.
The ministry has condemned the brutal attack, and pledged to provide assistance.
There are still an unknown amount of people trapped inside the mall, fanning fears of even more bloodshed.
"Every effort should be made to save the lives of those still in danger."
Somali militant group al-Shabab says the deaths were retribution for Kenyan involvement in Somalia and added that there will be no negotiations.
The international community has denounced the attack.
The U.S. State Department has called it "a senseless act of violence."
The United Nations, France and Britain also condemned the attack in the strongest possible terms and have offered to provide necessary assistance.
The tense standoff continues with the gunmen still holed up inside the mall.
The full horror of the attack is only likely to be known once the shopping center is secure.
