Two committees in the US House of Representatives are set to launch an investigation into reports that Washington has been spying on Israeli Prime Minister Benjamin Netanyahu.

Chairman of the House Intelligence Committee Devin Nunes said on Thursday that he asked the Director of National Intelligence and the head of the National Security Agency to provide lawmakers with documents and a briefing on the subject next week.

Nunes said the NSA usually informs Congress when it eavesdrops on conversations with legislators, but it failed to do so in the recent case.

"We're going to play this right down the middle and determine whether or not somebody did something wrong," Nunes said.

The Wall Street Journal reported Wednesday that President Barack Obama privately decided to maintain the monitoring of certain allies, including the Israeli prime minister.

The report said Washington was particularly concerned that Israel might be monitoring US negotiations with Iran to derail efforts to reach an accord on Tehran's nuclear program.

Netanyahu has been a vocal critic of the P5+1 group’s nuclear deal with Iran, sparing no effort to undermine the accord.

The NSA’s dragnet also “snared” communications between Israeli officials and pro-Israel members of Congress and advocacy groups.

Later on Wednesday, the chairmen of the House Oversight Committee and its national security subcommittee also sent a letter to the NSA chief, demanding answers regarding the surveillance of Israel.
