The Jewish communities all over the world will hold prayer vigils for the three kidnapped soldiers on Tuesday evening as part of a World Solidarity Day, local daily Ha'aretz reported.
This would be the largest solidarity event for the three soldiers, Ehud Goldwasser, Eldad Regev and Gilad Shalit, the report said.
Students in about 45 countries such as the United States, Chile, Venezuela, the Netherlands, France, Ukraine, Argentina, Brazil, Mexico and Uruguay will hold rallies simultaneously at Israeli time 21:00 (1900 GMT), it said.
Shalit was kidnapped near the Gaza Strip by Palestinian militants in June 2006. Less than a month later, Hezbollah fighters kidnapped Goldwasser and Regev, which sparked the Second Lebanon War, a 34-day conflict in which more than 1,000 Lebanese and 130 Israelis were killed.
Some 3,000 youths from all over the world took part in a formal ceremony in Jerusalem on Sunday evening, kicking the latest effort to secure the release of the three soldiers.
However, earlier this month, London-based al-Hayat newspaper quoted an French official as saying Israel is convinced Goldwasser and Regev are dead.
