Four more tourists missing in Algeria
Berlin - Four more Germans are missing in the Sahara desert in Algeria, police in their home town said on Wednesday, raising to 21 the number of European tourists listed as missing in north African country since late February.
Authorities in the south western German city of Augsburg said the four - two men and two women - had left home on February 22 for a trip of several weeks.
They were last seen on March 8.
Sixteen of the 21 Europeans listed as missing in the Sahara are German, and the foreign ministry has issued a public notice warning against travel to the region.
Another group of six Germans, four men and two women touring the desert in three four-wheel-drive vehicles, were reported missing on Tuesday.
Their relatives said they were "very worried" as they had not had any word from them since a phone call on March 17.
On February 21, 11 European tourists - six Germans, four Swiss and a Dutch national - went missing in southern Algeria.
Bands of smugglers are known to roam Algeria's southern Sahara, where they traffic in contraband across the porous borders with Niger and Libya.
Some, as well as arms and drugs traffickers also operating in the area, are thought to have links to a group of Islamic extremists.
