**Obama Presses Syria Strike at G20 Summit**
U.S. President Barack Obama will press world leaders at the Group of 20 summit in Russia for backing of a possible U.S. strike on Syria.
Russian President Vladimir Putin announced plans to add Syria to the agenda shortly after summit participants arrived Thursday in St. Petersburg.
In an opening session, Mr. Putin said some leaders had asked him to set aside time to discuss "very acute topics of international politics," in particular Syria. He said talks could take place during Thursday's working dinner.
The Syrian crisis is not on the official agenda for the two-day global economic summit, but Mr. Obama and other leaders have been discussing the issue on the sidelines.
The president is seeking broader support, both at home and abroad, for military strikes against Syria's government for allegedly using chemical weapons on its civilians.
** US Panda Cub is Female**
Smithsonian Institution officials say the two-week-old giant panda cub at its National Zoo in Washington is a female. They also revealed the cub's father is National Zoo panda Tian Tian.
The panda mother, Mei Xiang, was artificially inseminated with sperm from Tian Tian and from a San Diego Zoo panda named Gao Gao. A DNA sample was collected to determine the cub's father.
Zookeepers say the mother and cub are healthy, and the cub is starting to develop the distinctive dark markings in her fur around the eyes, ears and back.
China owns the rare pandas at the National Zoo. The cub is expected to stay at the zoo for about four years and will most likely be sent to China.
Mei Xiang's other surviving cub, a male named Tai Shan, was born in 2005 and sent to China in 2010.
The endangered pandas are well known for their difficulty in breeding and producing cubs.
