Another source of information is "News of Terrorism and the Israeli-Palestinian Conflict" contained in The Meir Amit Intelligence and Terrorism Information Center Newsletter.
Here is from the report of April 18-24, 2012:-
Rocket fire from the Gaza Strip targeting Israel's south continues (one rocket hit identified this past week); a yeshiva student was stabbed in Jerusalem, apparently for nationalistic reasons; two Palestinians from Nablus were detained at the Tapuach junction (south of Nablus) with four IEDs, a gun and ammunition in their possession.
On April 17 the Israeli prime minister met with a delegation of Palestinians who brought him a letter from Mahmoud Abbas. Salam Fayyad, the Palestinian prime minister, did not attend the meeting because relations between him and Mahmoud Abbas have become strained. Hamas denounced the letter and called on the Palestinian Authority to end its "useless contacts" with Israel.
The Palestinians have begun preparations for the May 15 marking of Nakba Day. Demonstrations and marches are planned for the territories and along Israel's borders.
Israel's South Important Terrorism Events

Infiltration from the Sinai Peninsula along the Israeli-Egyptian Border Prevented
On the afternoon of April 23 an IDF force engaged in routine security operations along the Israeli-Egyptian border identified a suspicious vehicle driving along the security fence and called to the vehicle to halt. When the driver and passengers ignored the order, the force opened fire. A number of suspicious persons were wounded and were taken to a hospital in Israel for treatment (IDF Spokesman, April 23, 2012).
Judea and Samaria
Stabbing in Jerusalem
On April 19 in Jerusalem a 20 year-old yeshiva student was stabbed in the stomach, incurring serious wounds. Two young Arab men were detained as suspects. The initial investigation revealed that the motive for the attack was apparently nationalistic.
Other Events in Judea and Samaria
On April 21 Israel border policemen saw two Palestinians about 17 years old alighting from a taxi at the Tapuach junction (south of Nablus), carrying a suspicious-looking bag. The policemen ordered them to halt but the two turned and ran. The youths, both residents of the Balata refugee camp near Nablus, were found to be carrying four IEDs, a gun and ammunition (Israel Border Police Spokesman, April 21, 2012).
There has recently been a rise in the number of stones and Molotov cocktails thrown at Israeli vehicles south of Jerusalem in the Gush Etzion district; on April 19 there were five such attacks. In one instance Palestinian youths threw stones and rocks at an Israel car at the Gush Etzion junction. One of the rocks hit the car and shattered the front windshield. Riding in the car were a couple and their two-year old son (Ynet, April 20, 2012).
