A family of six - including four children - have gone missing and are feared to be travelling to Syria, police say.
Father Asif Malik, aged 31, is believed to have left the UK with his partner Sara Kiran, aged 29, and their four children: Zoha, aged 7, Malik, aged 4, Zakariva aged 2, and Yahya.
The family, from Slough, were last seen in England on April 7, and were officially reported missing to police eight days later.
Thames Valley Police said they were "extremely concerned for the safety of this family, especially the four young children".
Mr Malik and his partner Ms Kiran left Slough without mentioning any holiday or travel plans to friends or family, which police said was "entirely out of character".
The family boarded a ferry from Dover to France in the early hours of April 7, and they then travelled south through Europe, possibly by train.
They are believed to have moved through Budapest, Hungary on or around Sunday April 12.
Police said they believed the family may be travelling to Syria after concerns were raised by Mr Malik's family.
