BUDAPEST - Prime Minister Benjamin Netanyahu admitted to the prime ministers of Hungary, the Czech Republic, Poland and Slovakia that Israel had carried out dozens of attacks against Hezbollah arms convoys in Syria.

"We blocked the border not only in Egypt but in the Golan Heights," he said. "We built the wall because there was a problem with ISIS and Iran trying to build a terror front there. I told Putin, when we see them transferring weapons to Hezbollah, we will hurt them. We did it dozens of times."

Although the meeting had been behind closed doors, Netanyahu's remarks were accidentally transmitted to the earbuds distributed among reporters, though his people discovered the transmission and shut it down within a few minutes.

Netanyahu launched a blistering attack against the European Union during the meeting, telling the premiers of Hungary, the Czech Republic, Poland and Slovakia that the EU's behavior toward Israel is crazy.

Netanyahu told reporters after his meeting with French President Emmanuel Macron on Sunday that Israel opposes the cease-fire agreement in southern Syria that the United States and Russia reached because it perpetuates the Iranian presence in the country. The prime minister noted that in his meeting with Macron, he made it clear to the French president that Israel was totally opposed to the cease-fire plan.
