ROME (Reuters) - Maltese patrol boats picked up a migrant dinghy with 80 people aboard but 20 others were reported to have died during the voyage, the Times of Malta said on Thursday. Along with southern Italy, Malta is one of the main points of arrival for migrants attempting the crossing from North Africa into Europe. The newspaper said the migrants appeared to have been at sea for some days. It said they reported there had originally been 100 people on the boat, but 20 died during the voyage. Lawless conditions in Libya have enabled people smugglers to put hundreds of small, unseaworthy craft to sea and thousands have died during the crossings over the years. An Italian coastguard vessel picked up a separate boat carrying around 70 migrants off the coast of Libya on Thursday, however arrivals from North Africa have slowed in recent months with more coming on larger cargo ships from Syria.
