The US military is weighing an increase in its presence in Yemen to better challenge al Qaeda in the Arabian Peninsula, building on momentum against the group after a successful offensive by Gulf allies, a top U.S. general told Reuters. US Army General Joseph Votel, who oversees American troops in the region, said in an interview that a variety of locations could be suitable for American forces but did not disclose potential sites or suggest a recommendation was imminent. 'We want to be able to work within a very secure environment to focus on the very (particular) mission we have there - which is principally focused on al Qaeda in the Arabian Peninsula (AQAP),' he said, speaking in Baghdad. 'We will try to posture the force where we can best do that.'
