Turkish army shells Syria in response to mortar attack
The Turkish army fired more shells across the border into Syria yesterday - and its government authorised Turkish troops to cross it if necessary.
Both actions were in response to a Syrian mortar attack.
The mortar shell fell on the Turkish town of Akcakale, killing three girls, their mother and another woman.
Turkish forces responded with a sustained bombardment of a Syrian military base near Tal Abyad. Several Syrian soldiers are thought to have died.
