Sayeeda Warsi, a senior minister in Britain¡¯s Foreign Office, resigned on Tuesday, accusing Prime Minister David Cameron¡¯s government of taking a ¡°morally indefensible¡± approach to the conflict between Israel and Hamas.

While the British government has repeatedly called for an immediate cease-fire in Gaza, Cameron has come under criticism from political opponents for what they say has been his reluctance to condemn Israel¡¯s actions in stronger terms.

Warsi announced her decision as Israel pulled its ground forces out of the Gaza Strip and started a 72-hour cease-fire with Hamas mediated by Egypt as a first step toward negotiations on a more enduring end to the month-old war.
