LONDON, June 6 (Xinhua) -- British Prime Minister Theresa May told Israeli Prime Minister Benjamin Netanyahu at Downing Street on Wednesday that Britain was firmly in support of the Iran nuclear deal following U.S. President Donald Trump's pulling out of the deal.

An official spokesperson for May issued details of the bilateral meeting, which came after Netanyahu had discussed the same issue with French President Emmanuel Macron and German Chancellor Angela Merkel.

May's spokesperson said: "They discussed Iran, where the prime minister reiterated our firm commitment to the Joint Comprehensive Plan of Action (JCPOA) as the best way of preventing Iran from developing a nuclear weapon. They agreed on the need to counter Iran's destabilizing activity in the region."

On Syria, the two agreed on the importance of seeing the conflict and deep humanitarian suffering brought to an end, and of preserving stability in other countries in the region, according to the spokesperson.

The spokesperson added that May told Netanyahu that she was deeply concerned by recent rocket attacks from Gaza and, as a friend of Israel, reiterated Britain's support for Israel's right to self-defense. She also said the Palestinians had a right to protest but it was important that these protests be peaceful.

"May said there was, however, concern about the scale of casualties in Gaza in recent weeks, and around Israel's use of live fire. The prime minister noted the importance of seeing the situation in Gaza swiftly alleviated and parties moving back towards direct negotiations for a two-state solution," said the spokesperson.
