Two Czech women tourists who were kidnapped two years ago in Pakistan have been released and have returned home, Czech PM Bohuslav Sobotka has confirmed.

Hana Humpalova and Antonie Chrastecka, both 26, were abducted while travelling on a bus in south-western Balochistan province in March 2013.

A Turkish organisation Humanitarian Relief Foundation (IHH) took part in the negotiations that led to the release.

The two were hosted at the IHH's office in Van in eastern Turkey for a time and then handed over to Czech officials and sent back to their home country. Kidnappings are not uncommon in Balochistan, both by militants and gangs seeking ransoms.
