United Nations undersecretary-general for humanitarian affairs and emergency relief coordinator, Mark Lowcock, who approved the allocation on Friday, said there must be reduction both in fighting on the ground and airstrikes, which have greatly intensified in recent weeks.
"Attacking journalists violates all global conventions and human rights treaties", the minister said.
He said many people in Yemen are now completely reliant on humanitarian aid to survive.
Deputy prime minister and foreign minister Abdulmalik Al-Mekhlafi said the Iran-backed rebels must immediately stop all crimes committed against politicians and civilians in Yemen.
"Islamic Republic of Iran has never had the means to send missiles to Yemen and the U.S. officials know that the missiles fired at Saudi Arabia have been developed by the Yemenis to have a greater range", he added.
In the meantime, Yemen's Information Minister Abdulsalam Jabir denounced Saudi-led coalition's Friday airstrikes that targeted members of the Yemeni Al-Masira satellite television and killed its cameraman. Saudi Arabia had 82 Tornados in service as of 2011, and contracts with BAE for upgrades to keep them operational through 2025.
The Houthi rebels seized Yemen's capital of Sanaa in 2014, forcing the country's internationally recognized president, Abd-Rabbu Mansour Hadi, to temporarily flee to Saudi Arabia.
The conflict - widely seen as a proxy war between regional rivals Saudi Arabia and Iran - has displaced more than 2 million people, caused a cholera epidemic and pushed the country to the brink of starvation.
