Yemen: Two car bombs kill at least 31 people, including 20 children

Sanaa, Yemen (CNN) -- Two car bombs killed at least 31 people, including 20 children, in central Yemen's Radaa city when suspected al Qaeda fighters targeted Houthi militants Tuesday, senior security officials and locals told CNN.

One car bomb struck a Houthi gathering point, but the other did not make it to the target and instead blew up next to a bus that was carrying children home from school, officials said.

All the killed children were under the age of 12, said Osama Sari, a prominent pro-Houthi activist.

Eleven Houthi fighters were killed, an Interior Ministry official said.
