The Defence Headquarters says there is no cause for alarm over recent security advisories by the United States and the United Kingdom.

The Director of Defence Media Operations, Major General Musa Danmadami and the Director of Defence Media Information, Major General Jimmy Akpor both gave the assurance at the biweekly media briefing in Abuja.

At the briefing, the army reported that over 40 terrorists were killed by military troops and a total of 145 other terrorists have surrendered in the last two weeks.

The US and Britain had last week warned of possible terror attacks in Abuja.
