Washington - The US government on Thursday advised Americans to avoid travelling to Yemen following the deadliest attack on a US embassy in more than 10 years.
The US State Department also authorized non-essential staff and their families to depart Yemen and said the security threat remains high because of terrorist activities.
Al-Qaeda is believed to be behind the attack on the embassy in Sana'a that left 16 people dead, including six militants.
US State Department spokesman Sean McCormack confirmed Thursday that a US woman, 18-year-old Susan Elbaneh, was among those killed outside the embassy ground.
