Turkey, US ”ready to invade capital”

Turkey’s President Recep Tayyip Erdogan has suggested he and the US are ready to drive so-called Islamic State (IS) from its Syrian stronghold of Raqqa.
Mr Erdogan said US counterpart Barack Obama floated the idea of joint action against the militants when they met at the G20 summit in China.
He said Turkey would have “no problem” with such action.
Last month Turkey launched an operation inside Syria, targeting both IS and Kurdish rebels.
Turkish-backed militia drove IS from the border town of Jarablus, but Turkey has also been concerned with checking the advance of Kurdish forces whom it regards as terrorists.
The offensive continues, and Deputy Prime Minister Nurettin Canikli said Turkish forces might push deeper into Syria after securing a stretch of land along the border.
