Israeli Prime Minister Benjamin Netanyahu and President Barack Obama met for the second time in a month as the two attended the UN’s Climate Change Summit in Paris Monday.

The two leaders bumped into each other at the sidelines of the conference after the group photo up of some 150 world leaders, walking the corridor and schmoozing for around 10 minutes, according to sources close to the Israeli Prime Minister. Secretary of State John Kerry joined towards the end.

The WH pool did not mention anything other than the president “shook hands with… Bibi.” But the Prime Minister’s Office tweeted out several pictures of the two engaged in a conversation and gesturing.

Netanyahu and Palestinian President Mahmoud Abbas also shook hands and exchanged a few words as they were standing in the same row during the photo op. This marked the first interaction between the Israeli and Palestinian leaders since they last met in 2010.
