Yemeni tribesmen holding four French tourists hostage have threatened to kill them if their demands for the release of jailed relatives are not met. Yemen deployed troops on Monday to try to free the tourists captured in the east of the country on Sunday. The hostages are reportedly in good health. Scores of tourists and foreign workers have been kidnapped in Yemen over the last decade by tribesmen demanding better living conditions or the release of prisoners.
Most have been released unharmed. President Ali Abdullah Saleh has vowed to crack down on abductions. At least two convicted kidnappers have been executed this year as a deterrent.
