A senior security source said to Newsyemen that experts of the Lebanese Hezbollah party arrived in Sana'a a few days ago in a secret mission.
The source confirmed the arrival of a group of Lebanese experts to Sana'a, through a smuggling operation by land.
Lebanese elements are likely to be charged with studying the status of differences among the Houthis group, assessing risks and prolonging Houthi control over the Capital Sana'a.
