Two women ¡ª an Indonesian and a Vietnamese ¡ª will be charged on Wednesday with murder over the killing in Malaysia of the estranged half-brother of North Korea¡¯s leader, Malaysia¡¯s attorney general said.

Police have said the women smeared VX nerve agent, a chemical on a U.N. list of weapons of mass destruction, on Kim Jong Nam¡¯s face in an assault recorded on security cameras in the Malaysian capital¡¯s airport on Feb. 13.

U.S. and South Korean officials believe Kim was the victim of an assassination orchestrated by North Korea. He had been living in exile, under Beijing¡¯s protection, in the Chinese territory of Macau, and had criticized the regime of his family and his half-brother Kim Jong Un.
