The Latest: Obama says weakened terror groups still a threat

NAIROBI, Kenya (AP) — The latest on President Barack Obama's visit to Kenya (all times local):

5:10 p.m.

President Barack Obama says terrorist organizations like al-Shabab are still able to harm civilians despite progress by the U.S. and others in weakening their networks.

Obama is speaking in a joint news conference in Nairobi, Kenya, with Kenyan President Uhuru Kenyatta. He says the world has decreased the group's control in Somalia and undercut its operations in East Africa. But he says that doesn't mean the problem is solved.

He says groups that are willing to target civilians and are prepared to die can still inflict damage. He's calling for more intelligence-sharing between Kenya and the U.S. to identify and prevent threats.

Obama is also drawing a connection between good governance and security. He says he told Kenyatta that U.S. experience teaches that rule of law and embracing civil groups is even more important amid security threats like al-Shabab.

Obama also says that the situation in South Sudan is "dire" and that the recent elections in Burundi weren't credible.

President Barack Obama says his administration will propose a federal rule banning the sale of almost all ivory across state lines.

Obama is speaking in a joint news conference in Nairobi, Kenya, with Kenyan President Uhuru Kenyatta.

He says the proposed rule is part of a U.S. effort to fight poaching in Africa. An estimated 100,000 elephants were killed for their ivory between 2010 and 2012.

The proposed U.S. Fish and Wildlife regulation would prohibit the sale across state lines of ivory from African elephants and further restrict commercial exports. But it provides limited exceptions for interstate sales, namely pre-existing musical instruments, furniture pieces and firearms that contain less than 200 grams of ivory.
