RABAT, May 12 (Xinhua) -- Dozens of illegal Sub-Saharan African immigrants tried on Sunday to storm through the border fence between Morocco and the Spanish enclave of Melillia, official MAP news agency reported.

Moroccan public forces intervened and arrested 40 illegal immigrants while 50 others climbed the guarded fence to enter Melillia, MAP said.

A total of seven members of the Moroccan public forces and two Sub-Saharan immigrants were injured and rushed into a provincial hospital.

Thousands of illegal immigrants try to enter Ceuta and Melilla each year, hoping to get a better life in Europe.

Both cities have six-meter-high border wire fences separating them from Morocco.
