'Israel is imposing an air and sea blockade on Lebanon as part of a major offensive after two soldiers were seized by the militant group Hezbollah. Israeli warships have blocked Lebanese ports, and its international airport was closed after Israeli bombing. A Lebanese cabinet minister said the Israeli response was disproportionate, and called for a ceasefire. Raids on targets across south Lebanon have killed at least 35. Two have died in Hezbollah attacks on Israel.'
