A Western diplomat said there are noticeable reductions in Houthi attacks after big coalition strikes, but new supplies seem to keep coming in and home-grown production continue.
"You see this everywhere where you have Iranian groups - one of the first things will be to try to get their local manufacturing capability up and running. That might start with very basic artillery rockets and then progress," Binnie said.
Iran and the Houthis have close relations, and analysts say some of their weapons technology resembles Iranian designs. A Houthi delegation visited Tehran in August and the two sides exchanged ambassadors for the first time.
A senior regional official, who has close ties to Iran's decision-makers, told Reuters around 35 senior Houthi fighters were on that trip and received missile and drones training.

The Houthis also indicated that Saturday's attack on Aramco was made possible by on-the-ground informers.
"It came after an accurate intelligence operation, advance monitoring and cooperation from honourable and free people inside (Saudi)," the group's military spokesman said.
