On Tuesday, the Saudi-led coalition attacked the port of Al Mukalla in southern Yemen, targeting military supplies delivered from the United Arab Emirates to separatists from the Southern Transitional Council, Saudi news agency SPA reported, citing the coalition's statement.
The Saudi Foreign Ministry said on Tuesday that Riyadh is disappointed by Abu Dhabi's support of the separatist group, considering their advance in Yemen a threat to its national security.
In response, the UAE Foreign Ministry said that the country is concerned about Saudi Arabia's recent statement on the situation in Yemen and the UAE's alleged role in it.
