Air strikes hit the capital of Yemen, Sana & # 39; a, during the night and until Monday with witnesses who said that the bombings hit Houthi rebel positions.
A coalition led by Saudi Arabia that launched air strikes against the Houthis in Yemen since March 2015 is the only force known to carry out strikes in Sana'a.
Robert Mardini, regional director for the Middle East of the International Committee of the Red Cross, said that "the night was hard" in the city with mbadive clashes that included air strikes and artillery. He reported that Yemenis were trapped in their homes and that an ICRC medical warehouse was attacked.
The violence comes as an alliance between the Houthis backed by Iran and former President Ali Abdullah Saleh seems to have collapsed.
The two sides joined three years ago and spread to Sana & # 39; a, forcing the country's renowned president, Abdu Rabu Mansour Hadi, to flee the country and seek military intervention led by Saudi Arabia.
The Huzi political office accused Saleh of organizing a "coup" against "an alliance in which he never believed" after he offered to start talks with the Saudi coalition. In a televised speech, Saleh called for an end to the siege of Yemeni ports and offered, in return, "to turn a new page" and "deal with them in a positive way".
Clashes between combatants loyal to Saleh and The Houthis broke out for the first time last week when Saleh accused the rebels of badaulting his giant mosque in Sana'a and attacking his nephew, the powerful commander of the special forces, Tarek Saleh
David Mack, a former US diplomat, dealt with Saleh, who was removed in 2012 after more than 30 years in office. Now, with the Middle East Institute, Mack described Saleh as "one of the most intelligent political agents in the Arab world," and someone who felt he was unfairly pushed out of power by members of the Gulf Cooperation Council backed by the United States. .
"I still wished I had a chance to restore his reputation, which has been terribly, terribly damaged over the last decade," Mack told VOA. "He has gone from having the reputation of being this supremely capable political operator within Yemen to being someone who has just gained personal power and was willing to see tremendous suffering from the Yemenis in the process."
Secretary General of the United Nations, Antonio Guterres on Sunday urged the warring parties in Yemen to stop all ground and air badaults. The UN said the sharp escalation of armed clashes and air strikes in Sana'a has already resulted in dozens of deaths and hundreds of injuries, including civilians.
Fighting is restricting the movement of people and rescue services within the city of Sana'a. Ambulances and medical equipment can not access the injured and people can not go out to buy food and other necessities, said the U.N. Humanitarian workers can not travel and implement essential programs to save lives at a time when millions of Yemenis depend on aid to survive.
Yemen is one of the poorest countries in the Arab world and has become a humanitarian catastrophe with more than 10,000 deaths in the fighting and at least 2 million displaced people. An outbreak of cholera has infected almost 1 million people.
