British troops deployed as Taliban wrests Sangin: As the Taliban overran several key areas of the Sangin district in Afghanistan's Helmand, British troops were deployed in the country, though not in a combat role. 

The Taliban reportedly stormed Sangin's police headquarters, administrative headquarters, and the intelligence agency office, though several reports cited Afghan officials claiming the militants had not taken over the district. 

About 10 UK personnel have been deployed in Helmand to serve in an "advisory role", BBC reported. "These personnel are part of a larger Nato team that is providing advice to the Afghan National Army. They are not deployed in a combat role and will not deploy outside the camp," a Ministry of Defence spokesman told the channel. 

Some reports also suggested US Special forces have been sent to Helmand as well to aid Afghan troops in their battle against the Taliban. 

On Sunday, Mohammad Jan Rasulyar, Helmand's deputy governor, had taken to Facebook to alert Afghan President Ashraf Ghani that the province was in danger of falling to the Taliban.

Isis shells Syrian school, kills 9: Islamic State shelling of a Syrian school killed nine students, the Syrian Observatory for Human Rights said on Tuesday.

Boko Haram insurgency leaves 1 million children out of school: UNICEF, the United Nations' agency for children, said in its report on Tuesday more than a million children were out of school because of the Boko Haram insurgency in Nigeria and other African nations. 

Boko Haram has attacked scores of schools in the region over the last five years, besides abducting 276 girls from a school in Nigeria's Chibok. 

The UNICEF regional director warned that many of the children left out of school in Nigeria, Chad, Niger and Cameroon could move to radicalism and be recruited by terror groups, AFP reported.

While several schools have reopened since the African coalition forces pushed back the militants in several regions, nearly 2,000 are still reportedly closed in these countries due to the Boko Haram threat.
