(Updates with landslide seen as cause) SANAA, May 31 (Reuters) - Explosions at a military depot in Yemen on Thursday were caused by a landslide, a Web site run by the defence ministry said. No casualties were reported. "The explosions at a camp east of the capital Sanaa resulted from rocks falling on old ammunition in a storage facility at the camp located on a slope," the site, www.26sep.net, quoted a defence official as saying. "It was caused by rain." "So far there are no casualties," said the official. Fire trucks and police cars rushed to the area. Hundreds of people watched from rooftops as smoke billowed from the depot. Earlier this week, officials took reporters to the depot to display bombs, artillery, anti-aircraft guns and other weapons bought or seized from civilians as part of a crackdown in the Arab country where arms are openly carried. Yemen's cabinet launched a campaign last month to shut down shops selling guns without a licence. It said millions of dollars would be spent buying up weapons from tribesmen.
