Sudan's longtime ruler is defiant in the face of more than three weeks of protests demanding his resignation.
President Omar al-Bashir reiterated to a rally in western Sudan on Monday that a change of leadership can only come through elections.

Police on Monday detained at least 18 journalists, mostly from the independent Khartoum daily al-Jareeda. The arrests were made as the journalists gathered outside the newspaper's offices before heading to the headquarters of the domestic security agency to protest state censorship.
The street protests erupted on December 19, initially sparked by price hikes and shortages but which soon shifted to calling on al-Bashir's ouster. At least 40 have been killed in clashes.
