World leaders should strengthen relationships across borders and ensure intelligence sharing to curb the growing sophistication in global terrorism.

The plea became necessary following recent attacks in United Kingdom and other developed nations, which clearly showed a need for stronger global collaboration and review of security architectures across countries.

President Muhammadu Buhari who made the call while receiving the Egyptian Ambassador to Nigeria, Aseem Elseify, said Boko Haram attacks within West African countries and across the borders were brought under control after concerted efforts by leaders to ensure joint operations.

Clearly the threat of global terrorism is getting more sophisticated by the day so we need leaders to work together to stop the attacks,’’ he said.

President Buhari said bilateral relations between Nigeria and Egypt in education, training and trade had been historical, urging the new ambassador to work towards expanding and deepening the scope of the relationship.

In his remarks, the envoy said building partnership to tackle the security challenges faced by both countries would be one of his priorities.
