Ethiopian troops cross into Somalia, prepare for offensive against Al Shabaab

At least 3,000 Ethiopian troops have entered Somalia in anticipation of a fight against Al-Shabaab militants, according to witnesses.

Residents in the southwestern Gedo region said soldiers with tanks and armored vehicles began crossing the border Monday and have been seen in the town of Luq.

Authorities in the region earlier said forces are being mobilized for an offensive in areas still controlled by Al-Shabaab, including the group's last major stronghold the town of Bardere, according to a report by VOA.

Al Shabaab has lost much of the territory it once controlled in Somalia but still carries out large-scale attacks.

Ethiopian forces invaded Somalia in 2006 to oust an Islamic government and since then, Ethiopia has frequently sent troops across the border.

The Ethiopians often work in tandem with the African Union mission in Somalia, AMISOM, which played a major role in driving Al-Shabaab out of the capital, Mogadishu, as well as other areas.
