GENEVA, Oct. 27 (Xinhua) -- About 125,000 people have been displaced due to Pakistan's latest military offensive in the past two weeks, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said Tuesday.

    "What we've seen in the last two weeks is that Pakistan has experienced a second wave of large scale displacement," said Manuel Blesser, head of Pakistan's OCHA office, in a telephone conference with Geneva's U.N. headquarters.

    Internally displaced people (IDPs) have been fleeing South Waziristan since Oct. 13 in response to a military offensive against insurgents.

    "Our ability to act, monitor and implement is very hampered" due to lack of access to the conflict and displacement zones, said Blesser.

    As of Tuesday, 205,000 people from South Waziristan have been displaced by the conflict, less than humanitarian agencies' expected figure 250,000. An estimated 80,000 to 100,000 people continue to live within South Waziristan's conflict zone.

    "We have to keep in mind the vulnerable groups of civilians," Blesser said, warning against being "hijacked by headlines of what is going on in South Waziristan."

    Blesser was referring to the Malakand Division, where 800,000 IDPs remain, 680,000 in host communities and 120,000 in camps.
