British Foreign Secretary Philip Hammond said he was heading to Israel later Wednesday to explain the Iran nuclear deal in person and voiced hope Britain could reopen its embassy in Tehran this year.

Briefing parliament about the agreement unveiled on Tuesday, Hammond said he would speak to Israeli Prime Minister Benjamin Netanyahu on Thursday "to convey our message about this deal directly".

More than 50 child soldiers recruited by the Islamic State group in Syria have been killed since the beginning of this year, a monitoring group said Wednesday.

The Syrian Observatory for Human Rights said it had documented the deaths of 52 child soldiers, all under the age of 16, who had been part of IS's "Cubs of the Caliphate" program.

Israeli Prime Minister Benjamin Netanyahu suffered a major defeat in failing to stop a nuclear deal with Iran but he remains as defiant as ever even at the risk of further isolation.

While the world's major powers welcomed the deal finalized with Iran on Tuesday as a historic moment capable of setting relations with the Islamic republic on a new path, Netanyahu harshly condemned it.

Egypt's military said Wednesday its troops foiled a suicide car bomb attack targeting an army outpost on a highway between Cairo and the canal city of Suez.

The Egyptian affiliate of the Islamic State jihadist organization known as the "Sinai Province" claimed the attack on a Twitter account affiliated to the group.

Iran's nuclear deal with world powers is a sign of a common will to end conflict in the region and defeat the Islamic State jihadist group, Iraq's premier said Wednesday.

"Daesh seeks to drag our region into perpetual conflict," Haider al-Abadi said on social media, using an Arabic acronym for IS.

Kuwait's public prosecution has demanded the death penalty for 11 of 29 suspects charged over the suicide bombing of a Shiite mosque last month, a newspaper reported Wednesday.

Al-Qabas, citing informed sources, said two of the suspects are currently fighting with the Islamic State jihadist group which claimed the attack. 

A man was killed trying to plant a bomb targeting police in a Shiite village near the Bahraini capital, the interior ministry said on Wednesday.

The ministry, on its Twitter account, said the failed attack took place in the village of Ekr but it did not identify the man killed.

Loyalists of Yemen's exiled president, buoyed by their recapture of the airport, seized more ground in second city Aden Wednesday as they pressed their biggest fightback yet against Iran-backed rebels.

The offensive, dubbed Operation Golden Arrow, is the first major advance by the loyalists since Shiite Huthi rebels entered the port city in March, forcing President Abedrabbo Mansour Hadi into exile in neighboring Saudi Arabia.

U.S. President Barack Obama and Saudi Arabia's King Salman on Tuesday discussed the "urgent" need to end fighting in Yemen, hours after Saudi-backed loyalists retook control of Aden airport.

After discussion about a recently inked nuclear deal with Iran, the White House said Obama and Salman "also spoke about the urgency of stopping the fighting in Yemen and the importance of ensuring that assistance can reach Yemenis on all sides of the conflict."

The United States does not support the establishment of an autonomous Kurdish entity in northern Syria, the U.S. special envoy for the coalition against Islamic State extremists said Tuesday.

Kurdish fighters have made gains in war-torn Syria against the Islamic State (IS) group, notably in land close to the border in the north with Turkey, triggering concern in Ankara that the Kurds might attempt to establish their own state in Syria.
