UK police officials say there is indication that three missing Bradford women and their nine children have crossed the border into the territory controlled by ISIL terrorists in Syria.

West Yorkshire Police said one of the missing sisters has made contact with her family.

"We have received information that contact has been made with the family in the UK which suggests one of the missing adults may be in Syria…Contact has been made by one of the missing women and there is an indication that they may have already crossed the border into Syria but this is uncorroborated," West Yorkshire Police was quoted as saying by the British Media.

Meanwhile, the lawyer acting for the families of three British women has said UK police knew of risk Bradford women would join their brother in Syria.

Balaal Khan says West Yorkshire Police had been investigating the whereabouts of the sisters’ brother who had gone to the war-torn country two years ago. Ahmed Dawood is believed to have joined ISIL terrorists.

It is also claimed that counter-terrorism police had been closely monitoring the family since Ahmed Dawood’s departure. This has given rise to the speculations that police could have prevented the women from attempting to leave the country.

Khadija Dawood, Sugra Dawood, and Zohra Dawood, along with their nine children disappeared after travelling to Saudi Arabia earlier this month.

Their relatives say they have to investigate the disappearance of the women and their nine children on their own, as they received no answers form police since reporting the 12 missing on June 11.

UK police has already been under fire for inaction in preventing young Britons from joining terrorist groups in Syria and Iraq, with hundreds of young Britons already having joined the ISIL terrorist group.
