At least four people were killed in Colombia on Tuesday as rebel groups detonated bombs near police stations in the city of Cali and the neighboring Cauca province, according to authorities.

Iran said Monday it will soon present a counter-proposal on a nuclear deal with the United States, after it had described Washington's offer as containing "ambiguities".
