An attack on Turkish soldiers, which killed more than 30, inside Syria is increasing tension on its borders and prompting concern about where a new escalation might all lead.

An emergency meeting of NATO ended with it calling for Syria and Russia to halt their Idlib offensive.

The secretary-general voiced solidarity with Turkey and called on Syria and its ally Russia to stop their offensive but offered no additional support.
