According to the Yemeni media 'Al-Masirah', Mohammed Ali al-Houthi made the remarks in reaction to UK Foreign Secretary Jeremy Hunt's remarks regarding Al Hudaydah peace agreement.
'Hunt is aimed to improve the position of enemies of Yemen who caused crimes and hunger for Yemeni people,' he added.
He noted the fact that the UK plans are not in line with justice but serve US and Israel.
Due to its measures, the UK is not an unbiased mediator anymore, he reiterated.
Earlier on Friday Hunt in a Twitter message referred to his meeting with Yemen's Ansarullah Movement Spokesman, saying 'I welcome progress in Hodeidah port discussions but withdrawal of Houthi troops needs to happen SOON to maintain confidence in Stockholm and allow opening of vital humanitarian channels.'
The United Nations Security Council adopted Resolution 2451 to support the Stockholm Agreement on deployment of a team in order to facilitate monitoring and implementing the Agreement and establishing truce in important Yemeni ports.
The resolution mainly focuses on sending essential commodities to the Yemeni people, supporting the Stockholm Agreement, assigning the Secretary-General of the United Nations to implement it and observing the ceasefire.
The fourth round of Yemen peace talks kicked off in Stockholm, Sweden on December 6 with the attendance of the UN special envoy Martin Griffith and the government representatives. It agreed to establish truce in Yemeni ports of al-Hudaydah, al-Salif and Ayn Issa.
Saudi Arabia and its regional allies attacked Yemen in March 2015 to bring back to power the deposed president of Yemen Abdrabbuh Mansour Hadi.
Since then, the invaders have committed horrible war crimes against Yemeni civilians.
Earlier, Iranian Foreign Ministry spokesman Bahram Qasemi said Iran has given no commitments to any party or country over Yemen.
He added that Tehran believes in establishment of a ceasefire in Yemen and is trying to pave the way for sending humanitarian aid there and holding intra-Yemeni talks.
The Islamic Republic of Iran will spare no efforts in line with finding a peaceful solution to Yemen crisis and preventing continuation of humanitarian disaster in this country, Qasemi reiterated.
