VON PRESS Middle East: 'They are participating in the bombing of Yemen people,' says Yemeni Prime Minister.
It comes amid reported discoveries of Britain-made weapons in bombed parts of the country.
Aden's former governor Habtour claimed the UK Government cared more about making profits from arms sales than the humanitarian crisis enveloping his country.
He told Sky News: "They have sold cluster bombs to Saudi Arabia. They know the Saudis are going to drop them on Yemen [...] in Saadah and in Sana'a and other provinces.
"I don't think they are guilty of war crimes, I believe so. They are participating in the bombing of Yemen people."
Sky reported that a soldier had told them the army had found a number of UK-made cluster bombs and showed photos of British cluster bombs he said had been found in fields in the city, which have been shared widely locally.

A resident of Sa'adah, a city located on the border of Saudi Arabia which has seen some of the worst bombing of the civil war, was also recorded saying: "First we thought Britain was a first, but now we feel the British Government are criminals, because of what's happening here.
"They're committing crime: killing children and pregnant women."
Meanwhile, the US canceled the transfer of some arms to Saudi Arabia, amid worldwide criticism about civilian deaths and destruction from the Saudi military aggression in Yemen.
Even before the start of the conflict in March 2015, Yemen was suffering a humanitarian crisis, including widespread hunger that was brought on by decades of poverty and internal strife.
Around half of Yemen's 28 million people are "food insecure", according to the United Nations, and seven million of them do not know where they will get their next meal.
At least 11,400 people have died as the result of the Saudi campaign in the kingdom's impoverished neighbor since March 2015, according to the latest tally by a Yemeni monitoring group.
The offensive was launched to undermine the Ansarullah movement and reinstate Yemen's former president Abd Rabbuh Mansur Hadi, a staunch ally of Riyadh.
Last month, the Yemeni Houthi Ansarullah movement and its allies announced the forming of a new "national salvation" government, led by Aden's former governor Habtoor.
