A leader of al-Shabab, Somalia's Islamist militia, threatened to launch terror attacks across America if President Obama doesn't embrace Islam. 

"We tell the American President Barack Obama to embrace Islam before we come to his country,"  Fuad Mohamed "Shongole" Qalaf said during a radio broadcast from the town of Afgoye near the Somali capital on Monday, The Associated Press reported.

Al-Shabab has yet to launch an attack outside Africa, but Western intelligence sources have been monitoring the group's recruitment of young Somali-Americans.

About 20 Somali-Americans have traveled to Somalia to train with the terror group, and at least three are known to have carried out suicide bombings there.

In July, al-Shabab terrorists coordinated suicide bombing attacks in Uganda that killed 76.

The group has openly acknowledged its alliance to al Qaeda, and Western intelligence sources say it is harboring one of the masterminds of the 1988 bombings of U.S. Embassies in Kenya and Tanzania that killed 224 people.

Some analysts believe al Qaeda-linked Islamists are gaining ground across the Gulf of Aden in  Yemen.

A takeover of Yemen would affect the shipping route leading into the Suez Canal, used for much of the world's oil shipments.
