23 Prisoners Escape Yemen Prison - on FRIDAY

The Interpol News Release wasn't posted until two days after the escape. Apparently, the prisoners, with help from outsiders, dug a tunnel from the prison to the less frequented women's section of a nearby mosque.

My question: If the prisoners got out on Friday - why did it not hit the U.S. news until Sunday? Maybe there is some Interpol S.O.P. info that I don't know about - but the delay strikes me as odd.
