An Israeli defense official said the shipments have been going on for several months. He said much of the aid has been transferred through the United Nations, and other supplies are placed along the frontier so needy Syrians can get them directly.
The Israelis have not tried to hide the origin of the goods, and some items, including medicine and diapers, are made in Israel and have Hebrew writing on them, the official said, speaking on condition of anonymity because he wasn't authorized to release the information.
Israel has been carefully monitoring the Syrian war since it erupted in March 2011. While relations are hostile, the ruling Assad family has kept the border area with Israel quiet for most of the past 40 years. Israel is concerned that Assad's ouster could push the country into the hands of militant Islamic extremists or sectarian warfare, destabilizing the region. More than 100,000 people have been killed since the conflict began in March 2011, according to U.N. estimates.
The Syrian fighting, mostly errant fire, sometimes spills over into Israeli border communities, damaging property and crops, spreading panic and sparking fires. Israel occasionally retaliates.
Israel is also believed to have carried out several airstrikes on several weapons shipments headed to the pro-Syrian Hezbollah group in Lebanon. Israel has neither confirmed nor denied the airstrikes.
