The escalation in the unrest in Sana'a this week has led to the death of hundreds of Yemenis, the Washington Post reported yesterday.
The capital Sana'a has returned to "calm" according to the United Nation's humanitarian coordinator Jamie McGoldrick. The brief pause in fighting has allowed civilians to come out of their homes and restock on amenities and fuel, amid a "desperate" humanitarian situation.
"Progress has not been seen yet, but we hope that that advocacy and those strong messages will open up the port," McGoldrick said.
International organisations, including President Donald Trump have urged the Saudi-led coalition to open ports and allow food to be delivered in Yemen.
McGoldrick confirmed that 15 ships with humanitarian aid and commercial cargo are in the Red Sea waiting for permission to unload. Only two ships were allowed access to Yemeni ports after the Saudi-led coalition claimed it was lifting the blockade, McGoldrick said.
Impoverished Yemen has remained in a state of civil war since 2014, when Houthi rebels overran much of the country, including the capital Sana'a.
In 2015, Saudi Arabia and its Arab allies launched a massive air campaign aimed at reversing Houthi military gains and shoring up Yemen's embattled government.
Statistics from the UN have shown that more than 10,000 people have been killed in the war, while more than 11 per cent of the country's population has been displaced.
According to the World Health Organisation, there are 700,000 cases of cholera across Yemen amid the escalation and changing political dynamics since the killing of Saleh early this week by the Houthis.
