Two explosions ripped through a market in Nairobi earlier today, killing 10 people and injuring 70 more in the latest in a string of increasingly frequent terror attacks.

It was not immediately clear who was responsible for the attack but the capital has been besieged with attacks by the al-Qaida-affiliated Islamist group al-Shabaab.

The group are waging an insurgency against the Kenyan government because of the presence of Kenyan troops in neighbouring Somalia.

The attack comes just a day after British officials warned tourists to leave the coastal resort of Mombasa because of a heightened risk of terrorism.
