"The congress of the [GPC] central committee, that was scheduled for Sunday morning, has been delayed due to the threats by the insurgents [Houthis] to attack the site of the congress' holding. They are trying to hamper the congress' holding for fear of making important decisions such as the break with the Ansar Allah movement," the source said on Saturday.
Yemen has been engulfed in a military conflict since 2015, with the government of President Abd Rabbuh Mansur Hadi fighting against the Houthi rebels, backed by army units loyal to former Yemeni President Ali Abdullah Saleh. Since March 2015, the Saudi-led coalition of mostly Persian Gulf Arab countries, including the United Arab Emirates, has been carrying out airstrikes against the Houthis in Yemen under Hadi's request.
In November, tensions between the rebels and Saleh escalated. On December 4, shortly after reaffirming the end of his alliance with the Houthis, Saleh was killed by the Yemeni rebels.
