SANAA, Yemen — Yemen's Shiite rebels and security forces loyal to the former president launched a fresh offensive Monday against the southern city of Aden, shelling it and battling local militias, but were pushed back by at least two airstrikes on the fifth day of a Saudi-led air campaign, security officials said.
The rebels, known as Houthis, meanwhile accused the Saudi-led coalition of bombing a displaced persons camp in the northern rebel stronghold of Saada, killing 40 people, including women and children. The report was carried on the rebels' TV network.
However, witnesses said the camp -- used to house displaced people from an earlier conflict that ended five years ago -- is now occupied by Houthi forces and that most of those killed were fighters.
It was not immediately possible to resolve the conflicting accounts.
