Islamic State seize new territory in Iraq and Syria

Islamic State militants have seized the last Syrian government-controlled border crossing between Syria and Iraq, a Syrian monitoring group says.

Government forces withdrew from al-Tanf - known as al-Waleed in Iraq - crossing as IS advanced, the Syrian Observatory for Human Rights (SOHR) said.

The loss of al-Tanf to IS follows the group's takeover of the ancient Syrian city of Palmyra on Thursday.

IS has also been made significant gains in neighbouring Iraq, capturing the strategically-important city of Ramadi in Anbar province after weeks of fighting.
