A car bomb in front of a police academy in the Yemeni capital of Sanaa killed dozens of people earlier today security and hospital officials said.
The attack took place as several people gathered in front of the building for a police recruitment event, according to security sources.
The bombing is the latest in a spate of attacks on the Huthi fighters who overran Sanaa in September.
On Monday, a bomb wounded six Shiite militiamen in Sanaa at a Huthi police post on Monday. It came a day after a bombing claimed by Al-Qaeda killed four people, including a journalist, at a Huthi gathering in the mainly Shiite city of Dhamar, south of the capital.
Last week, a suicide bomber killed 49 people at a religious celebration organized by Huthi supporters in the militia-held but mainly Sunni city of Ibb further south.
The Huthis have met increasing resistance from armed Sunnis, including Al-Qaeda loyalists, since they swept south from the capital into Sunni-majority areas late last year and many times their forces have been thrown back by Al-Qaeda affiliated militias, often with increasingly heavy casualties.
Yemen has been hit by continuing instability since an uprising forced longtime strongman Ali Abdullah Saleh from power in 2012, with the Huthis and Al-Qaeda seeking to fill the power vacuum.
