Yaound:
The far north of Cameroon, where a double suicide attack killed at least 11 people on Wednesday, has been regularly targeted by Nigerian Islamist extremists from Boko Haram.
Over the past two years they have stepped up abductions and deadly raids in the frontier region with Nigeria.
Although weakened by an offensive by the Nigerian army and collaborating armies from neighbouring Chad, Cameroon and Niger, the insurgents have stepped up violence in the region of Lake Chad.
Abductions
February 19, 2013: A French family of seven, including four children, on holiday, is abducted by armed men on motorcycles. Boko Haram claims responsibility. The family is freed in April.
November 14, 2013: French Roman Catholic priest Father Georges Vandenbeusch is abducted. Boko Haram claims responsibility. On December 31 French President Francois Hollande says he has been freed.
April 5, 2014: Two Italian priests and a Canadian nun are abducted in their parish 800 kilometres (497 miles) to the north of the capital. The security forces blame Boko Haram. The hostages are freed in June.

On July 27, two attacks target the residence of a deputy prime minister, whose wife is abducted and the palace of the sultan of Kolofata, who is kidnapped with his wife and their five children. All the hostages are freed in October.
Cameroonian reinforcements

Offensive against Boko Haram
