Shlomo Goldwasser, father of captured IDF reservist Ehud Goldwasser, criticized the Israeli government on Friday morning, saying that it was "not doing enough" to secure the release of the two reservists captured by Hizbullah. During an interview with Army Radio, Goldwasser also urged Hizbullah to provide concrete proof for the welfare of Ehud and fellow captive Eldad Regev. "Those holding our children want to give over a message. What is simpler than sending us a tape, calling the Red Cross or showing them on television as the Iranians did. All this can be achieved with just one phone call," said Goldwasser. "To say that they (the Israeli government) are dong everything is not true."
