In a recent blog post I suggested that prayer for the wellbeing of Israeli soldiers should be included in Jewish schools and classrooms at this time. As the missile attacks on Israel's southern cities continue and with the Israeli army now engaged in a ground operation in Gaza, there is all the more reason for prayer.
Yediot Aharonot reports that the call for prayer crosses all politicaland ideological boundaries in Israel, ranging from the Eidah Haredit (the "ultra-Orthodox") whose leaders have issued a statement calling for reciting tehillim to the Masorati rabbinate who have penned a Mi-she-berakh prayer specific to this occasion.
The announcement from the Eidah Haredit calls on the community to recite tehillim and to include va-aneinu in Shemonah Esreh since aside from the specific request for rain (which Israel needs right now), va-aneinu includes a request for general issues. If va-aneinu is not readily available in your siddur, you can find it at http://he.wikisource.org/wiki/%D7%95%D7%A2%D7%A0%D7%A0%D7%95 or http://www.new.katif.net/news.php?table=city_news&page=3615
The Yediot Aharonot article also has a tefillah that they say was put together by Rav Mordechai Eliyahu.
