KUALA LUMPUR, Malaysia - Vietnam says the Vietnamese woman under arrest in Malaysia for allegedly helping to carry out the deadly attack on North Korean ruler Kim Jong Un's half brother thought she was taking part in a prank.

Doan Thi Huong is among two women arrested for the Feb. 13 airport attack on Kim Jong Nam, which Malaysian police say was carried out with the banned chemical weapon VX nerve agent.

Vietnam's foreign ministry said in a statement posted on its website that a representative from the Vietnamese Embassy in Malaysia met with Huong on Saturday and confirmed that she is Vietnamese citizen. She is in stable health.

According to the statement, Huong said she was tricked and thought she was playing a prank. The other woman arrested over the attack, an Indonesian, also says she thought she was taking part in a prank.
