In southern Yemen, government forces backed by U.S. advisers claim they are routing al-Qaida in the Arabian Peninsula and allied groups from territory that the militants had controlled over the past year.
This is the same al-Qaida that has tried to send so-called underwear bombers to attack U.S.-bound planes.
Just outside the town of Zinjibar, it's clear that fierce battles went on here. It's deserted. There are no people, but there are an enormous number of bullet and shrapnel holes in the buildings.
