Doctors at Safed’s Ziv medical center were greeted with an eerie surprise Thursday while treating two Syrian rebel fighters, after it was discovered that one of the rebels had an unexploded grenade in his pocket.

According to reports, the emergency room was briefly evacuated and sappers were called in to remove the explosive device.

The men had been transferred to the hospital earlier in the day with serious injuries and were expected to undergo surgery. One of the injured was suffering from gunshot wounds in the chest, the other with a gunshot wound in the abdomen.

“Apparently they were shot at close range, they have serious damage to their internal organs,” a Ziv medical center spokeswoman told Israel’s Channel 2.

“This is the first time such a thing has happened to me and I don’t remember such a case in the history of the hospital,” one of the medical center’s doctors was quoted by Channel 2 as saying.

Yesterday the Ziv medical center also received two wounded Syrian rebel fighters. One of the men died but the other is reportedly in stable condition.
