The meeting, which was attended by other legislators, is said to have lasted two hours and was held behind closed doors.
"We have been briefed properly but these are security issues we cannot really disclose any of it," Senate Leader, Ali Ndume said while speaking to journalists after the meeting, The Nation reports.
"Unlike before, the Senate was not abreast or updated on the efforts they are making; now we have very full, honest, open and transparent discussion on the activities.
