Al-Shabab fighters count their bullets in neighborhood of Mogadishu. Al-Shabaab, one of the strongest Islamic militias battling for control of Mogadishu, has gained ground in recent weeks, according to officials, and has started to flex its muscles beyond Somalia's border with terror strikes, kidnappings and recruitment drives.

"People are playing golf 20 miles from here, and yet we have a whole town under water." The aftermath of Matthew's deluge has caused normally tranquil rivers to swell to record levels.

[EX Q]: Behavioural ‘training’ has been proven to banish the embarrassing tics seen in young patients with Tourette’s syndrome (TS). Experts at Great Ormond Street Children’s Hospital (GOSH) say sufferers can be trained to control involuntary body movements – which can include blinking, head-jerking and grimacing – and reduce their incidence by a third. ‘We’re not saying this is a cure, but it will give people tools so they can live a normal life such as going to school and seeing friends,’ says Dr Tara Murphy, a consultant psychologist at GOSH. The treatment works by a therapist asking a child to rate their tics and select the most annoying. They are then taught how to build up awareness of when that tic is likely to occur.Children asked by therapists to rate their tics and select most annoyingTaught a 'competing response' so they don't give in to involuntary urgesAround 300,000 people suffer from Tourette's syndrome in the UK
