The United Nations envoy Jamal Bin Omar arrived on Wednesday in the Yemeni capital of Sana'a to discuss with top government officials and army commanders the obstacles facing the GCC-brokered power transfer deal.

His visit to Yemen comes after some relatives of the former President Ali Abdullah Saleh refused to abide by the deal and did not listen to decrees issued by President Abdu Rabu Masnour Hadi.

It aims to convince rebellious Saleh's relatives to change their current positions.

A source in the General People Congress Party, founded and headed by Saleh, said that Bin Omar's visit comes in response to an a request by the ten states sponsoring the GCC political settlement that eased Saleh out of power.

Bin Omar is expected to meet up with top governmental officials, including Hadi and Saleh's eldest son, Ahmed, and some dismissed military generals who refuse to date to hand over the command of the military institutions to the newly-appointed leaderships.

The unnamed official added that" the UN envoy's visit is the last chance for those hampering the deal before a security council meeting on Yemen. If they insist on sticking to their rebellious ground, they might face severe sanctions including, a universal note of arrest, and freezing their assets".

Upon his arrival, Bin Omar met with the Yemeni Foreign Minister, Abu Baker al-Qirbi.

During the meeting, they reviewed the latest developments in the Yemeni arena and the current obstacles hampering the implementation of the GCC-deal.

Al-Qirbi hailed the efforts exerted by Bin Omar in reaching a peaceful settlement in the country, and his role in helping defuse tensions between the conflicting sides.

For his part, Bin Omar stressed the need for committing to the GCC-deal by all sides and reaffirmed the UN supportive position for Yemen.
