Israel says a media building destroyed by one of its air strikes in the recent Gaza conflict was being used by the Hamas militant group to try to jam its Iron Dome missile defence system. The Jala tower housed the offices of Associated Press (AP) and Al Jazeera. Explaining the attack to AP in New York, Israel's UN envoy also offered help in rebuilding its offices in Gaza. The AP news agency welcomed the meeting but said it had yet to see evidence to back up the Israeli allegations. Hamas, the Palestinian militant group that controls Gaza, has made no comment yet on Israel's claims.
