Washington, Jan 13 : US President Joe Biden has said that there will be further retaliation against the Houthis if the group continue with its "outrageous behaviour". Biden made the remark on Friday after the US and the UK launched dozens of airstrikes across Yemen overnight. The US President said that the strikes were a success and that he thought the Houthis were a "terrorist" group, the BBC reported. According to Houthis, over 70 missiles were launched at Yemen during the strike. "They (US and UK) committed an idiocy with this treacherous aggression," said Houthi spokesman Mohammed Abdulsalam. "We're not interested in a war with Yemen," said White House national security spokesperson John Kirby. However, he added that Biden "won't hesitate to take further action to protect our troops and our facilities and international commerce". Friday's attacks had the backing of US-UK allies including Canada and Australia, the British news broadcaster reported. /IANS
