The ongoing siege of Gaza by the Israeli government looked set for a worrying escalation following a visit to Gaza by the emir of Qatar. Just three days earlier, Israel's navy had boarded a Gaza aid ship and used tasers on activists. Sheikh Hamad bin Khalifa al-Thani entered Gaza via Egypt's Rafah border crossing on October 23. Israeli leaders condemned al-Thani's visit, the first by a foreign head of state since 1999. Al-Thani promised $400 million in aid projects to Gaza, undermining Israel's economic blockade.
