UPDATE 1-Foreign captives held by Philippines militants appeal for help

(Adds comment from Canadian government, company, paragraphs 7,
8)
MANILA, March 10 (Reuters) - Three foreigners kidnapped by
militants in the Philippines nearly six months ago have appealed
to their governments for help to secure their release, as their
al Qaeda-linked captors issued a one month deadline for their
demands to be met.
The three foreign men, who Philippine authorities have
identified as two Canadians and a Norwegian, were shown in a
video clip, along with a Filipino woman kidnapped with them,
crouching on the ground with gunmen standing over them.
"To the Canadian prime minister and to the Canadian people
in the world, please, do as needed to meet their demands, within
one month or they will kill me, they will execute us," said one
of the men who identified himself as John Ridsdel, a Canadian
mining consultant.
The three men were handcuffed and were thin, bearded and
shirtless. The video clip of about a minute and a half was
posted on a Facebook (NASDAQ:FB) page linked to Philippine Islamists.
The four were kidnapped from a beach resort on a southern
island last September. They are believed to be held in the
jungle on Jolo island, a stronghold of the Abu Sayyaf militant
group.
Another of the men, who identified himself as Robert Hall,
another Canadian, said he did not know how much money their
captors were demanding but he appealed for help quickly.
A spokeswoman for Canada's foreign minister said the
government was aware of the video but did not want to comment or
provide new information in case it endangered the captives.
Calgary-based TVI Pacific TVI.TO , where Ridsdel was a
semi-retired consultant, declined to comment.
The third man, who identified himself as Norwegian Kjartan
Sekkingstad, made a similar appeal.
It was the third time the militants had released such video
appeals from the captives.
In November, Ridsdel said in a video the militants were
demanding one billion pesos ($21 million) for each of them.
A militant spokesman appeared in the latest video to issue a
one-month ultimatum though he did not specify demands.
"We will do something terrible against these captives," said
the masked spokesman, who gave the date as March 8.
The September raid on the resort was a reminder of the
precarious security in the resource-rich southern Philippines
despite a 2014 peace agreement with the largest Muslim rebel
group that ended 45 years of conflict.
Abu Sayyaf militants are holding other foreigners including
one from the Netherlands, one from Japan, and an Italian
missionary.
