Yemen has been on high alert all week for a possible attack by Al Qaeda in the Arabian Peninsula.
The militant group known as AQAP is believed to be al Qaeda's most dangerous franchise in the region, which is why the United States is targeting its members with so many drone strikes.
The BBC's Yalda Hakim recently visited the coastal town of Zinjibar in southern Yemen.
"The people there feel helpless," says Hakim. "They're dealing with three different fronts. Al Qaeda on the one hand, then they've got the Yemeni military who have a grip over the town. And of course these drones hover overhead at any given time. But people there told me that they're equally as scared, if not more, of the drones than they are of al Qaeda."
