Yemen announced the Houthi rebel group was behind last month’s deadly attack on Aden airport

Explosions in Aden airport killed at least 28 people and more than 100 were wounded last Dec. 30 just as Yemen’s newly formed government arrived from neighboring Saudi Arabia.

Ibrahim Haydan, Yemen’s interior minister said the rockets were directed by a GPS-guided navigation system, he stressed that “only the Houthi militia has this system in Yemen through Lebanese and Iranian experts.”

“It was proven with conclusive evidence that the aim of the attack was to kill all government staff and civilians present at the airport,” Haydan said.

The Houthi group is yet to respond to the minister’s claims.

It had earlier denied responsibility for the attack and blamed it on the Saudi-led Arab Coalition in Yemen.
