The UK has called for a political process to include all factions in an attempt to achieve stability in Yemen, warning of a human catastrophe in the country.
The UK Foreign Ministry has also strongly condemned the attacks on Houthis mosques in Sanaa, the Yemeni capital.
“The UK continues to believe that an inclusive political process is the best way to achieve long-term stability, avoid civil war, economic collapse and a humanitarian catastrophe in Yemen,” Tobias Ellwood, the UK foreign minister for the Middle East said.
In a statement, Ellwood condemned “in the strongest terms the appalling bomb attacks at the two mosques in Sana’a and a mosque in Sa’ada.”
The suicide bombing attacks have killed more than 135 people and seriously injured many more during the Friday prayers.
Four suicide bombers attacked the Badr mosque, in the south of Sanaa, and the al-Hashoosh mosque, in the north of the capital.
Al-Murtada Bin Zayd Al-Mahtowry, prominent Shiite Houthi cleric and the imam of the Badr mosque, was among those killed.
The militant Islamic State group claimed responsibility for the attacks.
“Such violence against civilians can never be justified,” the statement said.
Ellwood underlines the UK support for President Abd Rabou Mansour Hadi, who moved from Sanaa to to Aden, southern Yemen.
Hadi’s residence in Aden was attacked by warplanes in the last two days.
London urged all sides “to refrain from the further use of military force and violence.”
The UK is a co-founder and chair of Friends of Yemen Group which was established early 2011 with the aim to develop a coordinated international strategy to help settle the Yemeni crisis peacefully.
The UK, a permanent of United Nation Security Council, is also overseeing the file of the Yemeni crisis at the UN.
London and FYG have supported the Gulf Cooperation Council – a sponsored initiative which was signed in May 2012 to solve the Yemeni crisis.
Yemen has suffered from political instability for many years. The violence has escalated since the Houthi military movement gained control over nine of the 21 provinces, including the capital.
