Israeli officials have been very careful not to broadcast more than very local images of the rocket impacts in Haifa. It's obviously critical that Hezbollah be denied that kind of information - any knowledge of where the missiles are falling can be used to aim at Haifa's vulnerable chemical plants and oil refineries. Guess what news channel's reporters were picked up by Israeli officials for taking very broad, very precise images of the missile sites and beaming them directly to TV stations around the Muslim world.
Reshet B TV seems to have had this story first, and broadcast it over evening TV. Officials noticed an Al Jazeera team being a little too eager in their work: the camera crew seemed intent on taking very broad pictures of entire areas around the impact sites. The behavior was suspicious enough that the officials picked up the crew for questioning. The story has also made it to the web, and Walla is carrying the next stage of the story - the Al Jazeera whining (Hebrew):

It's not the first time Israel has had to address Al Jazeera's less than entirely journalistic motives.
