The UN special envoy to Yemen Jamal Benomar submitted on Tuesday his report on transition progress in the country in which he said the transition is on the right track despite security concerns and obstruction attempts.
Benomar said President Abdrabu Mansour Hadi has proved to be competent to lead Yemen during the transition period, but challenges faced in the country including the security situation, an unprecedented humanitarian crisis and unresolved conflicts are still affecting the democratic transition.
In November, Yemeni parties signed a power-transfer deal brokered by the GCC and backed by the UN after the mass protests against the former regime.
The deal has been applauded and seen as a model at a time when the Arab Spring is continuing to sweep some regional countries.
On his last visit to Sanaa, Benomar failed to convince Tariq Saleh, a nephew of ex-president who is the commander of the third brigade, to hand over the brigade.
Saleh has been resisting a decree by Hadi replacing him and his act has been considered within obstruction acts affecting the political transition in the country.
"Latest developments, referring to the rebellion of military commanders, have revealed the tension causes remain and pose grave threats to stability in Yemen," he said.
"The patience of the international community has started to run out and those encouraging obstruction of the deal from behind the scenes will be sanctioned," he told the session of the UN Security Council on Yemen.
Furthermore, the UN envoy said an all-inclusive dialogue, scheduled to take place during the second phase of the transition period, is very important and can help keep a smooth democratic transition on right track in the country.
"Dialogue, for which good preparations have got underway, can make it or break it in Yemen".
Hours before the UN session on Yemen began, reports emerged the EU was taking measures to freeze assets of Yemen's ex-leader Ali Abdullah Saleh and his family in case the UN Security Council would decide to sanction them.
