SOUTH African Monique Strydom, held by Muslim rebels in the Philippines for more than two weeks along with 20 other people, is pregnant, according to a Filipino abducted by the same group. Strydom, whose husband Carel is also being held by members of the Abu Sayyaf group, is two months pregnant, the Filipino hostage, Andy Diamante, told three French reporters. Diamante also said that the 21 hostages are well under the circumstances and have not been mistreated by their captors. The South African couple and 19 other people were seized by Abu Sayyaf gunmen on April 23 from a Malaysian diving resort and taken to Jolo in the southern Philippines.
