A drone attack on a Yemeni government base by the rebel Houthi movement has reportedly killed at least six soldiers and injured several senior officials.
A video appeared to show one drone exploding above al-Anad base, in Lahj province, during a military parade.
Reports said the rebels had targeted personnel from the Saudi-led coalition backing the government.
The attack comes a day after the UN special envoy to Yemen said the warring parties had largely been adhering to a ceasefire agreed last month around the Red Sea port of Hudaydah, which is crucial to the delivery of aid supplies.
