The Yemeni military pushed into Ansar al Sharia-controlled Zinjibar and secured several areas in the city center after a six-hour battle that killed 65 militants on April 24. The military hit the city with airstrikes and artillery on April 23 before sending in army and security units supported by civilian fighters to clear the town. Yemeni military forces moved in from multiple fronts. The 119th Infantry Brigade, approaching from the southwest, was able to secure the outlying city of al Kod. The 25th Mechanized Brigade, stationed southeast of Zinjibar, cleared the southeastern approaches to the city. The 201st Mechanized Brigade approached from the north and cleared the surrounding areas. The 39th Armored Brigade entered the city center from the east, securing several buildings on the morning of April 24. Forces moved cautiously once inside the city to avoid mines laid by Ansar al Sharia. Yemeni troops then moved to clear government buildings. The 135th Infantry Brigade has been redeployed to reinforce the troops in Zinjibar. Ansar al Sharia denied that the army has made any gains, while military sources say the army is poised to retake the entire city. Yemeni forces were able to take portions of Zinjibar in July and September of 2011, but were ultimately unsuccessful in liberating the regional capital.
