Ethiopia has blamed a perceived lack of support from the international community for the withdrawal of troops from parts of Somalia. Earlier this month, Ethiopian soldiers abandoned areas of south-western Somalia, including the strategic town of Tiyeglow, where they were helping in the fight against terror group al-Shabaab.

"The international community also has a responsibility either to train or to support the Somali national army in whatever way they promised, and if they do not make good on that promise and [the] Somali national army fails to discharge their responsibilities then of course, as they say, nature – and al-Shabaab – abhors a vacuum, so they'll just move in," Ethiopian communication minister Getachew Reda said, according to the BBC.

Reda said the Ethiopian contingent was not part of the African Union Mission in Somalia (AMISOM), but reassured Somalia it would assist "in any possible way to fill the vacuum".

He also denied allegations that the decision to pull out troops was linked to a six-month-long state of emergency declared in Ethiopia in October, following months of unrest.

Al-Shabaab fighters have already recaptured Tiyeglow. The militants also regained control of the towns of El-Alif and Halgan, in the Hiran region, shortly after Ethiopian troops were evacuated from the area.

AMISOM has been accusing of failing to tackle the al-Shabaab insurgency.
