MADRID - A reported 1,000 sub-Saharan migrants on Tuesday morning tried to storm the border fence between Morocco and the Spanish enclave of Ceuta, armed with sticks and stones, but were pushed back by police officers from both countries, Spain's Efe news agency reports. At least three Spanish officers and 10 Moroccans were injured.

The fresh attempt to storm the double barrier surrounding the Spanish enclave took place at around 6 am. Security forces from both countries were on high alert after yesterday some 187 sub-Saharan migrants were able to push their way through the Tarajal crossing by running in a compact group. One Spanish officer was wounded.

According to Ceuta Guardia Civil chiefs, this morning's attempt was violent with migrants brandishing sticks, hand-made spears and sharp objects and throwing stones at the officers.

The enclaves of Ceuta and Melilla in Moroccan territory are today the main entry points for illegal migrants in Spain.
