At least 29 civilians including eight children were killed today in Turkish air strikes on an Islamic State group bastion in northern Syria, a monitoring group said. The Syrian Observatory for Human Rights said the strikes were carried out on the flashpoint town of Al-Bab, which Turkish forces have been seeking to capture for weeks in the biggest test of a four-month incursion into Syria.<br/><br/>The raids came a day after 14 Turkish soldiers were killed by jihadists around Al-Bab, in the country's biggest loss of the campaign so far. Turkish troops entered Syria on August 24 in support of pro-Ankara Syrian rebels, with the aim of ousting IS jihadists as well as Kurdish militia from the border area.<br/>
