British Foreign Secretary David Cameron has suggested that Britain may strike Houthi targets in Yemen again if the group continues to attack ships in the Red Sea.
Britain may strike again at the Houthis in Yemen
Cameron said Britain had no choice but to attack Houthi targets in Yemen.
Cameron said Britain had delivered "warning after warning" to the Houthis before joining the US-led strikes this week.
He said prices in the UK would rise if the Houthis blocked vital trade routes. That is why London is participating in the campaign against the Houthis to protect "freedom of navigation".
He also suggested that Britain may strike Houthi targets again if their attacks continue.
The Houthis are a political and military group that controls a large part of Yemen, including the capital. Iran, Israel's sworn enemy, supports them.
The Houthis declare their support for Hamas and say they target any vessel bound for or belonging to Israel.
