Thousands of people in Yemen have taken to the streets in celebration following the departure of president Ali Abdullah Saleh to Saudi Arabia.
However, it is unclear if the president will return to Yemen following weeks of unrest.
He is in Saudi Arabia for treatment for injuries received during an attack on his presidential compound on Friday.
Following the latest developments, the British Foreign & Commonwealth Office continued to urge Britons to leave the country by any means available.
“We advise against all travel to Yemen and strongly urge British nationals to leave now by commercial means,” read a statement.
“If you do not leave the country now, while commercial carriers are still flying, it is extremely unlikely that the British government will be able to evacuate you or provide consular assistance.
“Our current ability to provide consular assistance is very limited.”
The FCO went on to warn routes in and out of the capital Sana’a and the other major cities may be blocked and airports closed or inaccessible at little or no notice.
Gulf Air, Egypt Air, Emirates, Qatar Airways and Turkish Airways are among those offering flights out of the country.
The situation on the ground remains tense.
While thousands throng in the streets in celebration, explosions are reported in Sana’a and Taiz in the south.
Yemeni vice-president Abd-Rabbu Mansour Hadi has replaced Saleh for the duration of his absence.
