The U.S. embassy in Sana'a expressed astonishment and disappointment over the accusations by the Houthi Group that it, namely U.S. envoy Gerald Michael Feierstein, had been involved in the deadly blasts in Jawf and Saada last week.

The accusations were absolutely ridiculous and baseless, the embassy said in a press release on its website. "The accusations were not honorable to the families which lost their relatives and friends in the two car-bomb attacks that killed almost 26 and injured other Shia people."

The U.S. embassy in Yemen strongly condemns such heinous attacks against innocent civilians on religious ceremonies, the statement said.

Last week, two bombings took place in northern Yemen with one targeting on Wednesday a convoy on its way to celebrate Eid Al-Ghadir in Jawf killing almost 24 and injuring several others. The other targeted on Friday Houthi followers traveling in Saada to show respect at a funeral killing two and injuring almost eight.

The Houthi Group accused the U.S. and Israeli intelligence services of orchestrating Wednesday's attack and said Feuerstein provided funds for sheikhs and tribal leaders on his visits to some areas including Amran to carry out Friday's attack.

Its information bureau said the attacks bore the hallmarks of the U.S. and that none could benefit from them but the U.S.

It also claimed the attacks were aimed at bringing about sectarian conflicts and disturbing the public security and eliminating lives, adding that the recently-appointed U.S. ambassador is implementing a U.S. plan similar to the one he carried out while in Pakistan.
