ANKARA, March 9 - Turkey said on Monday that NATO air defences shot down a second ballistic missile that was fired from Iran and had entered Turkish airspace, warning it will take any necessary steps against threats.

This marks the second Iranian ballistic missile in the last week that has targeted the south of Turkey, which is a NATO member and Iran's neighbour. Ankara had warned Iran against attacking again on Saturday, but has not suggested it wants to formally call on alliance members for further protection.
