Aid to Gaza increases - and so do rocket attacks

As night follows day, the number of rocket and mortar attacks are increasing as Israel continues to loosen restrictions on Gaza.

Today, Israel plans to send more than double the amount of aid to Gaza that it has been sending - some 350 trucks. The types of items being sent in has also increased dramatically - here are the figures from last Thursday (via email):

At the exact same time, the number of rocket and mortar attacks has increased just as dramatically:

6/21 Two attacks, at least 5 mortars
6/24 12 mortars (3 fell short) and one Qassam rocket
6/28 - 1 mortar
6/29 - Two mortars claimed
6/30 - Qassam, causing damage

Think there is a causal relationship?
