A ballistic missile fired by Yemen's armed Houthi group at Saudi Arabia was shot down yesterday near the south-western city of Khamis Mushait. Arabiya said on its Twitter account, without giving details. The Saudi-owned al-Arabiya channel reported that it was the second ballistic missile fired from Yemen this month.<br/><br/>A Saudi-led coalition fighting the Houthis in Yemen has closed air, land and sea access. It said the move is meant to stop a flow of Iranian arms to the Houthis, who control much of northern Yemen. The blockade has cut food imports to seven million people on the brink of famine.<br/><br/>Saudi Arabia and its allies, who receive logistical and intelligence help from the United States, accuse the Houthis of being a proxy of Iran. The coalition has launched thousands of air strikes against the Houthis who still control much of Yemen's main population centres including the capital Sanaa and the strategic port and city of Hodeidah.<br/><br/>The conflict has led to one of the world's worst humanitarian crises and killed at least 10,000 people. <br/><br/>
