Yemen campaign will drag on into 2016

Significance

However, events on the ground in recent days, including the intensification of air strikes by the Saudi-led coalition and the Huthis' defiant firing of a Scud missile into Saudi Arabia, signal that both sides are determined to continue the seven-month long war.

Impacts

• Even if Sana'a falls, the Huthis may fight on in their heartland.
• The war is empowering local groups who are likely to complicate attempts to reimpose central authority.
• In Saudi Arabia the campaign's failure would be blamed on Defence Minister Mohammed bin Salman, reducing his prospects of becoming king.
• Southern separatists, al-Qaida and Islamic State group will be empowered by the conflict.
