Beirut, Lebanon ? Four Israeli missiles slammed into a refrigerated warehouse where farm workers were loading vegetables Friday near the Lebanon-Syria border, killing at least 28 people, according to officials at the Syrian hospitals where the dead and wounded were taken.

At least 12 other workers were wounded in the attack.

More were likely buried under the rubble, said Ali Yaghi, a Lebanese civil defense official at the scene. A bulldozer was brought to the site to try to uncover any survivors.

Arab television channels showed videotape of Lebanese soldiers and orange-garbed rescue workers hauling body after body out of the ruins of the warehouse. Many of the victims were dismembered and their bodies appeared scorched. Some of the corpses were laid out in rows, covered with heavy blankets. The nearby orchard was badly damaged; crates of fruit lay in a jumble nearby.

The attack occurred about two miles inside the border when five Syrian refrigerator trucks arrived at a vegetable warehouse to load peaches and apples for the Syrian market, said drivers and witnesses. They said there were about 150 people at the warehouse when the attack occurred.

The toll of dead and injured was provided by the emergencies services at the al-Qusair National Hospital on the Lebanese-Syrian border and the National Hospital in the Syrian city of Homs.

Syria’s official news agency, however, reported that 33 were killed, 23 of them Syrians. The Syrian dead included 18 men, two elderly women and three young girls, it said. Ten were wounded.

Syria said the U.S. administration was directly responsible for the deaths because of what Syrian information minister Mohsen Bilal said was Israel’s reluctance to call for an immediate cease-fire despite international demands. He called the deaths “massacres.”

Israeli army spokesman Capt. Jacob Dallal said the army suspected the warehouse was used for arms because they tracked a truck believed to be carrying weapons going into the building from the Syrian side, stayed inside for about 90 minutes, then returning to Syria.

Some of the workers were killed by flying rocks and shrapnel after the missiles struck, Yaghi said.

Yaghi said civilian pickup trucks were dispatched to haul the bodies, as well as the wounded to the Syrian hospitals. Roads toward hospitals in Lebanon had been cut off by Israeli airstrikes earlier Friday. A Lebanese ambulance also carried some victims, he said.

The agricultural site was run by a Lebanese company.

The strike occurred near the town of al-Qaa, about six miles from Hermel, a Hezbollah stronghold that has been hit by Israeli airstrikes at least three times. The first attack was three days after fighting began 24 days ago.

Hermel was largely cut off from the rest of the country after two Israeli air raids destroyed a bridge on the Orontes River in the Bekaa Valley a week ago.
