The Office of the Spokesman of the UN Secretary-General issued a statement on October 22nd, local time, saying that 12 foreign UN employees detained in Sana'a, the capital of Yemen, had left Sana'a by plane earlier that day, and the other three foreign employees were free to move or travel.
The statement said,There are still many United Nations-related staff members, as well as non-governmental organizations, civil society institutions and diplomatic missions, detained by the Houthi armed forces。
Jemen's Houthi armed forces attacked a residential district of United Foreign Employees in Sanaa on Tuesday, detaining several UN officials and released some of the detainees in the following days.
Houthi leader Abdul Malik Al-Hussein said in a televised speech on the 16th that there are "dangerous spy groups" within humanitarian organizations operating in Yemen. They assisted Israel in air strikes in Sana'a in late August, resulting in the death of many senior officials of the Houthi armed forces. The United Nations denies that its staff were involved in espionage.
