Israel keeps quiet over alleged strike on Syria Video>> U.S.: Israel launched airstrike on Syria JERUSALEM, May 4 (Xinhua) -- Israeli Foreign Ministry and Israeli Defense Forces (IDF) refused Saturday to comment on foreign reports about an Israeli attack on a missiles convoy in Syria overnight Thursday. U.S. media reported Friday that Israel attacked a convoy carrying missiles from Syria to militant Hezbollah in Lebanon, citing high-ranking U.S. sources. On Saturday, both spokesmen of the IDF and of Israeli Foreign Ministry refused to comment on the alleged attack. However, Israeli media reported that an unnamed Israeli source had confirmed to foreign media that Israel is behind the attack. In response to U.S. reports, Israeli embassy in the United States said that "what we can say is that Israel is determined about preventing the transfer of chemical weapons or other means of warfare that are game changers by the Syrian regime to militant factors, especially to Hezbollah in Lebanon." Lebanese media reported that the Israeli air crafts have been flying in Lebanon for four days in a row.
