Greater Manchester Police seeking 'Syria trip' twins
Police have confirmed they are trying to trace missing twin teenage girls from Greater Manchester who are reported to have travelled to Syria.
The 16-year-old girls were reported missing from their home on 26 June.
Police said the twins flew from Manchester Airport to Turkey but it had been unable to establish their location now or why the girls had gone abroad.
The Sun on Sunday said it understood the Muslim twins had travelled to Syria.
It said their brother was a fighter for the extremist militant group Isis.
'Secure girls' wellbeing'
Greater Manchester Police (GMP) said in a statement: "Since their departure the girls have been in contact with their family.
"We are attempting to confirm their current location and secure the well being of both girls."
The force said officers are also providing regular support to the family.
Some 6.5m people have been displaced in Syria since an uprising against President Bashar al-Assad began in March 2011.
About 500 UK Muslims are thought to have gone to fight in Syria.
However, more than 100 imams in the UK have appealed to British Muslims not to travel to Syria and Iraq.
In an open letter they said they had come together as a unified voice, to urge people not to fall prey to sectarian divisions or social discord.
