Mogadishu, Somalia ? The Islamic group that controls Somalia’s capital arrested two of its own militiamen for killing two people who were watching a World Cup soccer match, the group’s leader said Thursday.

The two detained militiamen allegedly shot a teenage girl and a businessman who defied their orders to stop watching the match Tuesday between Italy and Germany.

The increasingly powerful Islamic group has forbidden some Somalis from watching television or movies, in line with its strict interpretation of Islam.

But its leader, Sheik Hassan Dahir Aweys, whom U.S. officials have branded a terrorist, said the group has not officially banned television or movies.
