Israeli strikes and tank fire in Gaza have killed at least four people, including two children, according to hospital officials. This comes a week after a U.S. delegation asked Israel to reduce attacks. On Monday, a strike hit a building in the Bureij refugee camp, killing a 4-year-old. And tank fire in the south killed a 10-year-old. Elsewhere, Israel's military said it targeted Hamas weapons storage facilities inside mosques. Israel says it targets militants and responds to ceasefire violations. Meanwhile, Israeli officials have expressed concerns over kites being flown into southern Israel from the Palestinian territory.
