It was his first public response to Tuesday's interception by Israel of a Libyan executive jet. He said any planes forced down would be searched for what he called "Israeli terrorists". Ordinary passengers would be released. Israel has modified air routes in and out of the country as a security measure, it was announced today. News index 102/202 Newsreel 119/219
