Yemen sacked at least one high-ranking security chief on Monday afternoon following the deadly suicide bombing in Sanaa earlier in the day.
According to the BBC, Yahya Saleh was dismissed by President Abd-Rabbu Mansour Hadi. Saleh is the nephew of ousted President Ali Abdullah Saleh and the head of the Central Security Organization.
Gen. Ammar Saleh, director of the National Security Bureau and other one of the ex-president's nephew's, was also reportedly fired along with Abdul Malik al-Tayyeb, head of central security.
More than 90 people were killed when a bomber wearing a military uniform blew himself up during the rehearsal for Tuesday's National Unity Day parade in the capital.
We were in a parade, suddenly there was a huge explosion. Dozens of our men were killed. We tried to help them, Col Amin al-Alghabati told Reuters.
The suicide bomber was dressed in a military uniform. He had a belt of explosives underneath, he added.
Al Qaeda reportedly claimed responsibility for the attack, which occurred 10 days after the start of the military's new offensive against the terrorist group in Abyan province. Most of the causalities came from Saleh's Central Security Organization.
This is a real massacre, Ahmed Sobhi, one of the soldiers who witnessed the explosion, told the Associated Press. There are piles of torn body parts, limbs, and heads. This is unbelievable. I am still shaking. The place turned into hell. I thought this only happens in movies.
