Islamic State is reported to have used car bombs to injure at least 50 people, with some killed, near the mosques and the headquarters of Yemen’s Houthi Group in Sanaa on Wednesday.
Four blasts were heard in the capital. Saudi forces conducted air strikes against the Houthi military bases in Yemen.
According to peace talk delegates in Switzerland, there was no progress on the second day of a UN-sponsored push to create a truce.
Witnesses said that the explosions sounded like air strikes. Some found cars and people screaming after the explosions.
The Islamic State used its social media accounts to state that they were responsible for the attacks. It was one of the most serious Yemen has faced throughout the years.
Suicide bombers from the IS had also killed at least 137 worshippers and wounded during Friday prayers on March 20 this year.
The IS had increased its Yemen presence as the al-Qaeda and other militant groups were overshadowed by it.
AQAP, a Sunni militant group, faces dissolution as a US strike drone had killed their leader Nasser al-Wuhayshi.
Meanwhile, Houthi fighters have destroyed the home of a Senior Politician Abdel-Aziz Jubai as he attended the Geneva talks as part of the exiled Yemen government.
