Ghana and Togo are the next targets for Islamist militants following high-profile attacks this year in Burkina Faso and Ivory Coast, according to a memo from Ghana's Immigration Service.

The memo calls for better border protection in the latest sign of a heightened government response to the threat to West Africa by militants based in northern Mali who have stepped up a campaign of violence in the last year.

It says the National Security Council Secretariat (NSCS) has evidence from neighboring Ivory Coast from the interrogation of a man suspected of orchestrating an attack on March 13 in which 18 people were killed.

"Intelligence gathered by the ... NSCS indicates a possible terrorist attack on the country is real. ... The choice of Ghana according to the report is to take away the perception that only Francophone countries are the target," said the memo, dated April 9 and published by Ghanaian media.

It ordered immigration agents on the northern border with Burkina Faso to be extra vigilant and said patrols should be stepped up along informal routes between the two countries.
