This is a brief report out of YNET here but I did want to throw it up - it seems odd to me. I can't quite figure out what is going on but my gut feeling is that the Israelis have perhaps located some Hamas that were involved in the Jerusalem seminary massacre. I'll go ahead and excerpt the whole story here:
Report: IDF encircling 10 Hamas members' homes in
Palestinian sources reported
Tuesday night that the IDF was encircling 10 Hamas members' homes in different
areas in the West Bank city of Ramallah. According to the sources, one of the
houses belongs to Hamas lawmaker Dr. Myriam Salah, who is jailed in Israel.
Another house belongs to senior Hamas member Omar Hamdan.
reported it was conducting a routine detention activity. (Ali Waked)
So there you have it - this may be worth keeping an eye on. If they do nab some Hamas for what suspect, this could send shockwaves throughout the region - and what timing, with good old terrorist-sympathizer Jimmy Carter coming to kiss the golden ring of Hamas.
