Erdogan dismisses Sweden's NATO aspirations at Vilnius summit.

Turkish President Erdogan has refused to ratify Sweden's NATO membership bid before the military alliance meets in July, stating that Sweden has not fully addressed his security concerns. Turkey accuses Sweden of being too lenient towards groups that Ankara says pose a security threat, including Kurdish armed organisations and people accused of associations with a failed coup attempt against Erdogan's government in 2016. NATO requires the unanimous approval of all existing members to expand, and Turkey and Hungary are the only countries that have not yet ratified Sweden's request to join.
