President Donald Trump will host Israeli Prime Minister Benjamin Netanyahu at the White House on Wednesday as tensions continue to rise across the Middle East and negotiations intensify over curbing Iran's nuclear weapons programme.

Netanyahu is expected to press Trump to pursue a deal that would not only halt Iran's uranium enrichment, but also cut its ballistic missile programme and support for proxy groups like Hamas and Hezbollah.

The prime minister has long argued that Iran represents an existential security threat to Israel and has pushed the US to curb Tehran's influence in the region.

Iran has suggested it is ready to limit its nuclear programme in return for sanctions relief, but it has rejected the other demands.
