Somali suicide threat to Kenya
Somali militant group al-Shabab has threatened Kenya with suicide attacks in retaliation for sending troops across the border in the wake of hostage raids.
A spokesman for the group said in Mogadishu that Kenya must pull its troops out.
Lines of Kenyan forces poured into Somalia over the weekend. Kenyan officials say the country has the right to defend itself from Somalia's most powerful militant group.
Al-Shabab said Kenyans should remember what happened in Uganda - a reference to the July 2010 bombings that killed people who had gathered to watch the soccer World Cup final on TV.
It said those attacks took place because Uganda has troops in Mogadishu with the African Union military force.
