BAGHDAD, Oct 19 (AFP) - The kidnapping of the head of international charity CARE's Iraq operations on Tuesday was the latest in a wave of abductions that has seen about 150 foreigners seized since April.
More than 30 hostages have been killed by their captors.
Here is a list of foreigners still held captive or missing in Iraq, where scores of Iraqis are also estimated to have been kidnapped:

AMERICANS
-- A soldier, Private First Class Keith Matthew Maupin, 20, went missing in an attack on a convoy near Baghdad on April 9. A video later purported to show his "execution," but Washington says the film is "inconclusive".
-- Timothy Bell and William Bradley, employees of the Halliburton firm and its oil subsidiary, KBR, remain missing following the same attack.

BRITON
-- The British-born head of CARE International's Iraq operations, Margaret Hassan, was kidnapped in Iraq on October 19.
Hassan, who is married to an Iraqi and is a naturalized Iraqi citizen, has worked for CARE in Iraq since 1992 and has lived for more than 30 years in the country. Al-Jazeera television aired footage of Hassan, saying she had been kidnapped by an armed group which did not reveal its identity or state any demands.

CANADIANS
-- Iraqi-born Rifaat Mohammed Rifaat, 41, who worked for a Saudi company renovating Abu Ghraib prison, has been missing since April 8.

EGYPTIANS
-- Two Egyptian engineers working for telecom giant Orascom were snatched on September 23 in Baghdad, along with another six employees, four Egyptians and two Iraqis who were later freed. The company said on October 2 that the two were "in good health" and that efforts to free the pair were continuing.

FRENCH
-- Journalists Christian Chesnot and Georges Malbrunot were seized on August 20 along with their Syrian driver, Mohammed al-Jundi by a group calling itself the Islamic Army in Iraq. The French government said on October 13 that the two were alive.

JORDANIANS
-- Jordan is investigating reports that two of its nationals -- Ziad Rifai, a 44-year-old father of six, and truck driver Mahmud Ismail Zeidan -- were abducted near Fallujah. Another Jordanian, Hisham Talab al-Ezza, was freed by his kidnappers and returned home last week after 12 days in captivity after his family paid a 50,000-dollar ransom.

KUWAITIS
-- A hostage speaking with a Kuwaiti accent and who said his name was Saydan Saadun warned in a televised video on June 5 that truck drivers should not work for the "infidel" US-led military forces.

LEBANESE
-- Four Lebanese remain held hostage or missing in Iraq, according to the foreign ministry, after two were released last week. In all, 26 have been kidnapped, one of whom was killed by his abductors. Two of the men are being held by the Islamic Army in Iraq, which is also holding two French journalists.

SOMALIS
-- Al-Jazeera television reported on July 29 that a Somali truck driver, Ali Ahmad Mussa, had been kidnapped. It said on August 2 that his captors had decided to release him but there has been no news since.

SWEDES

SYRIANS
-- Mohammed al-Jundi was seized along with the two French journalists, and truck driver Awaad Mohammed was taken captive on August 14 near the northern city of Kirkuk.

TURKS
-- Turkish nationals, driving convoys of supplies across Iraq to US army bases, are an easy target for kidnappers. Ten were freed last week but several remain captive and at least one has been killed.
