BLITZER: South African authorities are keeping close tabs on Oscar Pistorius. Lisa Sylvester is monitoring that and some of the top stories in THE SITUATION ROOM right now. What's the latest, Lisa?</s>LISA SYLVESTER, CNN CORRESPONDENT: Hi, Wolf. South African officials saying the Olympic track star must undergo at least four random tests for drugs and alcohol in the next few months to make sure that he is complying with his bail terms. Pistorius is charged with fatally shooting his girlfriend, Reeva Steenkamp. He must check in with his probation officer twice a week. And in other news, the Syrian regime says it is ready to talk with the country's armed rebels, but that's drawing skepticism from the U.S. and from the opposition. Secretary of State John Kerry says it's difficult to take the regime's offer seriously when it's dropping missiles on its own people. Rebel leaders say they will attend an international meeting on Syria scheduled for later this week in Rome. Cuban leader Raul Castro says he will step down in 2018. He made that announcement after lawmakers re-elected him to a five-year second term. The 81-year-old Castro took over from his ailing older brother, Fidel Castro. Cuba's next leader likely will be this man, Miguel Diaz-Canel Bermudez. Lawmakers have selected the 52-year-old as first vice president. That puts him next in line for the presidency. OK, how about this, for just inspiring your next workout. A 101-year-old marathon runner has wrapped up his running career the way he started it, with a race. He completed a 10-k in Hongkong over the weekend. He began running when he was 89 years young to overcome depression from the death of his son. The great, great grandfather has completed nine marathons and has raised thousands of dollars for charity. Isn't that great though? He started running when he was 89 years old. Now 101, just completed a 10-K. So that's inspiration for you, Wolf.</s>BLITZER: That's amazing. It's a real inspiration. Thanks very much, Lisa.
