The Israeli military says its aircraft have attacked smuggling tunnels along the Gaza-Egypt border. Palestinian officials say tunnels have been damaged but have not reported any casualties. They spoke on condition of anonymity because they were not authorised to talk to the media. The Israeli military says the pre-dawn attacks on Sunday were in retaliation for rocket fire on southern Israel the previous night. It says it will not tolerate attacks on Israeli territory. The Israeli-Gaza border has been tense but fairly quiet since Israel's three-week military offensive against Gaza's Islamic militant Hamas rulers earlier this year.
