Security forces and guerrillas battled Thursday for a sixth straight day in northern Namibia, and officials said South Africa, Angola and Cuba were seeking to hold an emergency meeting to halt the fighting.

At least 210 guerrillas of the South-West Africa People's Organization and 24 members of the South African-led security forces have been killed since fighting broke out Saturday, police said today.The Soviet news agency Tass, reporting from Luanda, Angola, quoted a SWAPO official as saying only 38 guerrillas had been killed.

South Africa, which has ruled Namibia for 74 years, has said if the crisis is not quickly resolved it may suspend a U.N.-supervised plan to grant Namibia independence. The transition was to have begun Saturday.
