Fighting gripped Yemen's second city Aden today as the UN envoy was expected in the rebel-held capital Sanaa to press his efforts to broker a ceasefire.
Saudi-led warplanes bombed rebel positions, killing eight people, while rebel rocket fire killed six, including a child, officials said.
Aden was the last refuge of President Abedrabbo Mansour Hadi before he fled to Saudi Arabia in March and has been a key battleground ever since.
