Al-Qaeda-linked militants are disrupting Yemen's political situation and could harm global security, the UN envoy there has warned.
Speaking to the media Jemal Benomar said insurgents were trying to disrupt efforts to strengthen the government.
He made the remarks a day after a suicide attack in the capital Sanaa killed 10 police cadets.
Benomar warned that global security could be affected if the international community did not support Yemen.
Since Ali Abdullah Saleh stood down as president last year, Islamist militants have taken advantage of the instability resulting from the popular uprising that forced him out.
