In 18-nation military exercise in Jordan, troops practice retaking border seized by militants

Troops participating in an 18-nation drill have staged mock exercises, including recapturing an international border and a ship seized by militants.

Some 10,000 troops are taking part in the two-week "Eager Lion" exercise hosted by Jordan for the fifth year. Many are from countries that have joined a U.S.-led military coalition against Islamic State extremists. The group has captured large areas of Syria and Iraq, and seized the Iraqi city of Ramadi over the weekend.

Maj. Gen. Rick B. Mattson, head of training in the U.S. military, said Monday the military drill "shows there is a common interest among all 18 nations for regional stability and this is why we are here."

In a live-fire drill on retaking a border, a B-52 bomber attacked mock targets.
