Tensions are rising as a key US ally accuses Yemen's Iran-backed Houthi rebels of attempting to attack a major Islamic city. The accused group has denied involvement in the attempted attack. Condemnation has come from countries in the region, but no military support has been offered.

A crucial pipeline has been shut down for weeks due to attacks by the Houthis on infrastructure and shipping. Iran is also targeting ships in a major waterway. Further details on the situation and its impact on the global oil market are available from the source.

Oil prices remain a concern amid the ongoing tensions.
