The Israeli embassy in Berlin released a statement from the defense ministry in Tel Aviv, saying the defense ministers of the two countries had discussed Tuesday's incident.

The episode occurred when Israeli jets scrambled after a helicopter took off from a German frigate serving with a United Nations Interim Force in Lebanon (UNIFIL) task force. German Defense Ministry spokesman Thomas Raabe said six Israeli F-16s had flown very low over the German vessel and one of them fired two shots near the ship.

An Israeli army spokeswoman said the helicopter did not coordinate his plan with Israel before taking off. As a result, Israel sent fighter jets into the air, forcing the helicopter to return to the German vessel and land.

The Israeli military, however, denied having fired any shots in the incident, which happened near the border with Lebanon close to the border town of Rosh Ha'Nikra.

Israeli Defense Minister Amir Peretz telephoned his German counterpart Franz-Josef Jung Wednesday night to explain the incident, officials from both sides said, stressing a desire to maintain good cooperation.

Jung is due to pay a visit to Israel next week, but Tuesday's incident is not expected to cast a cloud over the talks, diplomats said.

The German vessels are overseeing an arms embargo against the militant Shiite Hezbollah movement, following an August 14 ceasefire that ended 33 days of fighting between Israel and the Lebanese group.

Overflights

Israeli jets over the past few days have intensified their activity over Lebanon by flying at low altitude and staging mock raids over areas in south and the capital, Beirut.

Such incidents are not considered serious in Israel, but UNIFIL's command has warned that the flights over Lebanon endanger the UN mission.

French UNIFIL commander Alain Pellegrini has reportedly asked the United Nations to provide his force with air defense artillery as protection against Israeli warplanes.

In another incident, a French patrol was forced to go on alarm stations early October after Israeli warplanes approached close to it and refused to respond to radio messages, Israeli reports said.

Scope of operations

In a related issue, the German defense ministry denied a report in Thursday's Süddeutsche Zeitung newspaper claiming that the rules of engagement for the task force had been changed, restricting the scope of its operations.

Israel launched a wide-scale offensive against Hezbollah on July 12 after Hezbollah captured two Israeli soldiers in a cross-border raid and killed five others. The hostilities came to an end one month later after the UN Security Council adopted resolution 1701.

The resolution calls for a ceasefire and the deployment of UN troops alongside the Lebanese army along the border with Israel.
